There is this girl in my school, who has been in a couple of classes of mine. We would say hi when we saw each other and occasional basic pleasantries every so often (i.e. how is your day going? Etc…). Then out of no where she began getting much friendlier, talking to me more, physical contact, and stuff like that and I have no idea what it means. Truth is I am not that fond of her, I wouldn’t even consider her a friend, but I can’t tell if she is flirting, or just being friendly, but she seems to think there is a connection there that I just don’t feel, but since I don’t know what her intentions are I have no idea how to respond or even if I should do anything. I am leaning towards assuming that she is flirting, but I am really unfamiliar with this kind of thing, is there any clear tell sign's or anything like that so can tell I can tell if she is flirting?
