Am i jumping to conclusions about this girl liking me?

Yeah so I was at my locker and these girls were talking a couple of lockers down. They said something about you-know-who and they weren't talking about voldemort. One of them left to go to their locker and then they saw me and started giggling and stuff. I think they were talking about me. I think one of their friends may like me? The two girls talking don't because one has a boyfriend and the other I have never talked to and she's ugly so i just hope it isn't her. I think it's one of their friends. This friend commented "nice shirt" when I wore my socialist shirt into school. She also was asking me for answers for a cl test a couple weeks ago and didn't talk to my friend who she is actually friends with. And i was walking down the hall and i'm pretty sure she said hi to me. I don't really talk to her except that one time in cl, so IDK. Am i jumpin the gun, people?
