So I recently started using higher quality shampoo and whatnot because I have long and awesome hair and hygiene is important. Anyway, I was hanging out with a friend of mine a while back and she walks right up to me and starts smelling my hair. Like, with no hesitation. She was running her fingers through it and playing with it and everything. I was under the impression that type of behavior is supposed to be a really intimate thing. Mind you, we are not at that level we are just friends. Is that the case or am I overthinking this and it's totally normal for women to just do that for no reason? Not that I'm complaining about it cause it was kinda nice.
