Is her laughing flirting??

I went to try in clothes today and it was toward the end of the day. This really cute girl came over to ist. She got the giggles and really started messing around pulling out ridiculous choices and then laughing hysterically. Her friend working with her was teasing her -why are youu giggling. It was actually really funny and fun. Do you think this was as a result of something between us. She def wasn't being mean and I felt we were having fun
