How to get a girls attention?

[565]

I sent her a message on Facebook yesterday saying..."Hey! I'm not sure if you remember me from _____. We were in the same art class sophomore year, I believe. How've you been?" This was my first message by the way and my first time I've talked to her on Facebook. She was active online twice today, but still didn't reply...some girls already answered this and said, she might be busy or creeped out. What should I do? Back in high school she told someone I was cute, but I never had confidence to talk to her back then. Should I comment on one of her pictures to get her attention and then she might realize I sent her a message?

She's not in a relationship.

You didn't message her; you posted to her page. That might be why she is "creeped out". That should have been a private FB email. Maybe you can try that this time.

there are two possibilities that will happen if you do it.
first:
you might catch her attention, and she might ask if she know you, or she may say that she probably remember you, and both of you will start chatting

second:
she might think that you are just a man that going crazy about her since high school and she might feel scared or annoying.

second option:
just let her be
maybe she dont want to reply because she busy
or
she want to see your reaction whether you crazy about her
so the best thing i suggest,
dont comment on her picture, just let her waiting for you, (unless she is not interested)
maybe she will be wondering who you are and reply your message...
