<human>: Okay. So I'm a junior in high school and I like this girl that's a senior.. We see eachother in the hallways occassionally and we take the same bus to school every other day.

I've had a crush on her for a while now but I never really knew her name until like 2 days ago when I found out her name (not from her though) so I added her on facebook and she accepted.

Since it's spring break and there's no school, I was thinking i'd message her on facebook, maybe strike up a conversation.. but the thing is - I have absolutely no idea how. 
I'm like really really inexperienced with girls. 
Also since she's older and finishing school this year maybe it'd be a little weird that a younger guy starts to message her? Plus exams are coming up and she's prolly gonna be busy, would I just be bothering her?

Give me a shortened version of the text
<bot>: I'm 17, she's 19, would it be weird that some younger guy that she doesn't know from school started messaging her?
