10 point for the best answer(I rlly need help)?

Ok I just started high school and I just finished the second day(I'm very shy btw)on the first day a group of girls came up to me and said hi remember me?(I went to the primary school there then I left. Yes it's a private school)and I said oh yeah I remember then turned back to my friend and continued talking to him(this was at recess by the way) and then after a few minutes another group of girls said almost the same thing but i said yeah then started talking to my friend again. The second day at school at recess a few girls came and sat next to me. The one siting next to me said hi in a nice voice and I said hi back to her and started to talk to my friend as I do. He said to me I'm mr popular lol. The girls talked to each other for a bit as they do.. Then walked away. And at lunch a girl said why did you leave the school? I said I don't know. Are these girls flirty or....?
