Is this girl interested in me, but is shy?

[LookAtTheSky123]

Hello.

Right, so every morning I take a bus to school. And meet my friends at a bustop close to my house. The past couple of weeks, I've just noticed a girl that goes to the same bustop as me, and I like her. :3
I'm still trying to work out whether she likes me back, and thought I'd ask on here.
A few times, out of the corner of my eye, I've spotted her taking a few glances at me. But not for long, I never have enough time to face her and catch her eye. One of the first few days I had noticed her, she was on the side of the bustop, and was sorting out her hair with a hair-band, and stayed there for a couple of minutes, and when she'd sorted it out, she sort of began to come from the side/back of the bustop and out to the front where the most people where.
I've also read, that sometimes when using body-language, you can work out whether a girl is interested if her legs are crossed, and the one at the top is pointing towards you, and hers always is pointing towards me (I could be wrong, it's probably just a coincidence).

My last hunch, is when she was sorting out her hair while sitting at the bustop, and she was trying to sort out her hair or something, and put her oyster card on her lap (An oyster card is this card we need to scan once we get on the bus if you're wondering. I live in London.) It fell off her lap onto the ground and she picked it up, I noticed her blushing and quickly (she always takes glances quickly) looking in my direction.

I haven't noticed anything that has made her think I'm a bad guy, nor do I recall myself being stupid or acting badly infront of her. (It's always in the morning anyway, and I'm quiet around then, haha.)

Could she like me back? Or is it just me that thinks this? If you could just tell me whether you think she likes me or not, and if she's shy, hiding it, etc. And how can I try and get her attention and maybe let her know I like her too? Any advice? I welcome all of it. :L
Btw, I know she is a school year below me, my friend in the year above me said she used to go to his primary school and she is two years below him.

P.S
First time I saw her, I had my glasses on. The third time, they where off and she watched me for a few seconds then. I always try to catch her eye, but when I turn she looks away. And oh, if you suggest I should just go and flat-out ask her, it's a bad idea. Because where I live, it's just simply considered strange to say that to someone that I've never even talked to.

Thanks.

Thanks guys. I will try to catch her attention and try the sentence starters that you suggested Alice
And I see now why she was behind the bustop trying to sort out her hair now xD

Thanks for all the replies, I still welcome any new ones.
Once again, thanks.

So first of all, I'm a girl, and I'm
going to give you a girls point of
view to your situation.
Yes, she definitely like you. The
body language thing is true,
though I've never thought about
it until now, I always do that
subconsiously to the guy I like.
I knew for sure she liked you
when she dropped the card and
blushed and it was YOU she
glanced at, a tell tale sign she
didnt want to make a fool of
herself in front of you.
The fact she is always fixing her
hair in front of you says she
wants it to look perfect for you.
And this is fidgeting, fidgeting
around you means she likes
you. I know this one for a fact!
I understand your P.S, it's weird
to walk up to a girl like that
where I come from too! So
here's a few much subtler
suggestions to get you started:
-talk to her in person first. I
dont care what its about, a
conversation starter could be
"you're the year below me,
arent you?" and if you are
friends or know any guys in her
year ask does she know them.
Then if shes appreciating the
conversation (if shes smiling in
other words) try a flirty turn in
the conversation by saying "of
course i bet you have a
boyfriend." if you want, when
she says no, say "really?! didnt
expect that. thats good." thatd
be a face to face way of telling
her youre interested.
Or you could take a much more
normal conversational approach
and introduce yourself, "i dont
know how i see you everyday
and still dont know your name."
whateve you want, up to you.
but id suggest having a face to
face interaction before the next
step.
-Add her on facebook, follow
her on twitter, whatever is the
rage in your town. then
message her, say hey, and bring
up anything you want, be flirty,
wink faces but not too much.
then at the end a common one
used on me is "hey im getting
off this now, but we could text
if i got your number?" and this
is the crucial part of knowing
youre in or not.
-texting will come naturally to
you two, as it does to everyone.
and if you or her arent old
enough for a mobile, you arent
old enough to date. the
conversations will get deeper
everyday, and sometime,
through text, you will be able to
ask her out.
hope this helped and hope it
works out for you! best of luck.
Alice
ps - lose the glasses. she prefers
you without them!

you know for me its very easy to tell because i am a shy girl and i do like a boy so you must know that theres a quite big chance she likes you because being a shy girl we dont tend to look at boys for long i always glance at my crush but not for long its extrememly embarassing to be caught so we are very very careful and whenever i feel i have done something embarassing in front of my crush i blush too, the best thing to do is try to talk to her, start by saying hi ( but dont just go up to her randomly and say hi because if u havent spoke to her and she likes u she will be a bit confused and scared) maybe if u know someone who hangs out with her this is ur opportunity to be near her and it not be so awkward then gradually start to have conversations, build it up so shes comfortable ( she is shy!) be patient!!! and then im sure u two can be friends this is where u will determine ur feelings and where its going and btw i live in bristol.. not too far from u!
