What’s her deal? Did I ever do something?

So I’m in a lab class where we partner up to do the labs. There’s a girl where I’m pretty sure she glances at me once in a while but I think nothing of it really. I sometimes look back to she if she was staring at me. Yesterday the class met up for the lab and someone said a funny story and we laughed and I was standing right next to her. She was looking at me while laughing but I was saying something to my friend.

Whenever I have a question, I go to the nearest person around. She was close by w her friend so I went up to ask them. I ask and she looks at me and looks away and just ignores me. then her friend answers. This has happened several times in the past also. Does she think I’m weird or something? Ik for a fact she’s ignoring me for whatever reason.
