Why does this girl act so weird around me?

Question

So there's this girl I've been interested in for a while. We've been friends for about a year now, but not like best friends. Anyway, I went to this school-sponsored fair, and she says hi, and we get to talking, and I'm keeping her laughing and smiling for the most part (only a few silent/awkward moments, few and far between) and she hangs with me for the whole fair. (I wasn't following her, she was following me.)

We texted a few times the next day,but when we got back to school, she smiled at me like once and then pretty much ignored me for the rest of the day. This became sort of a routine: Sometimes, she'd stop and talk and be smiling and laughing the whole time. Other times, she'll just walk right past without saying hi.

Then we had school pictures, and she hung out with me the entire time again, just like at the fair. After that, she starts doing the on again/off again deal just like before...

What's the deal here?

Answer 1

She likes you.  She doesn't know if you like her. Sometimes it feels as if you do and other times shes not sure if you like her or not.  Ask her out somewhere. Go on date. I say go for it!

Answer 2

she thinks you're ugly and is disinterested.  your mom payed her to talk to you, the days she ignored you were the days your mom couldn't afford her (not a good day for prostitution, i guess).
