This girl and I have been friends for a few months but mainly hang out in groups. We were playing pool, she kept repeatedly asking to be on my team and then hugged me a few times when we won. Days later, she then burst into my dorm room and asked if I could hear her singing, because apparently it would be "super embarrassing" if I did. Then just recently, we were walking back from dinner (other people had left a bit earlier) and she asked me if I was going to this winter dance coming up. Not sure, but it feels like especially when these are all happening in relation to one another, that they could be signs.
