all right, so, the calling, yeah, sure, she's into you. The email, also a good sign. The hair?? Huh? I do that all the time...not a sign from me. (I hope, re-thinking all the men I talked to today) The touching. I touch people all the time...if I know them...so, maybe yeah, if she touches you and doesn't know you? Like in a bar/club? Oh, hell yeah. But outside of that, if this is a friend/someone you hang with? Not so sure. She might be familiar enough to touch. But otherwise, yeah, the touching would mean you could ask for a number. LOL That's always a sign, right? If you ask, she says no, or gives you 867-5309....
I think it's all relative. She might be interested until you say something, maybe do something...then nope. Or she might be interest, but not in a drive by, or she might be interested but not be too sure on you. So, maybe the eye contact, the active listening (is she really listening to you?) and/or talking to you at all. These are all subtle, but some of the other posts are pretty clear - tongue down your throat, hand around you parts!
all works, right?
