How would I reply to this?

[just another girl]

I got a tour of my new high school today by an incoming junior girl. I'm an incoming freshman.
I'm naturally shy when I first meet people, so I spoke quietly and didn't say much.
I just saw on her twitter that she said I was "boring". That really hurt me. I'm going to get Tour Part 2 from her next week.
How should I reply (and not seem boring/shy) to someone saying something like
1 "This teacher gives a lot of homework"
2 "This is the library, you can like eat or sleep here if you're lazy."
3 "The seniors set off a stink bomb and it smelled so bad!"
These are of the things she told me today, but whenever she said something, I just replied with a quiet "Oh" or quietly chuckled.

Please number your answers 1-3 and post some possible non-boring replies that I could have given. Only kind ones please.

Thanks
nope she doesn't know I saw her twitter; I don't even follow her :'(
