<human>: Could you distill the essence of the text into 1-3 sentences?

I've liked this girl for several months now and I really want to ask her out, but I really don't think I've caught her interest, even though some of my friends think she's totally into me. But these friends haven't even met her in person, they've just figured that she fancies me by things I've told them, so that's a huge reason why I'm cautious.

She allows me to sit next to her every time she has an empty seat next to her in a class or during a play rehearsal, but that doesn't necessarily mean anything. We do have friendly conversations, so it's not like I just sit down and say nothing. 

There were a couple instances that my friends interpreted as flirting: when we were taking down a set for a musical, she came up to me and reached into her pocket, told me to hold out my hand and dropped a bunch of screws in it. I don't know how my friends think that's flirting, but whatever. There was also another time where I went into a student lounge area, where she was napping on a couch. I chatted with a couple friends who were on the couch and eventually she woke up and started throwing things at me "because you're standing there." I can see how that can be flirting, but I dunno.

I haven't really noticed anything about her body language or eyes that would tell me that she's into me, and I haven't even gotten her number, as I don't even know how to get it for I don't want to end up making an awkward encounter since most of the time we're around each other, we're around people we both know. I haven't had any experience with women, so I'm completely lost here.

I did declare my major a few weeks ago and it happens to be the same as hers, but that's not why I chose it. That said, I'll be around her a lot more often next semester, so should I wait and get to know her better then or act now?
<bot>: My friends who have never met this girl say she's into me, but for obvious reasons, I'm unsure. Ask her out now or wait?
