I have another question. Suppose you're minding your own business being awesome and dancing in a dance / club context. Sometimes a girl will walk past me, very obviously stroking me but just walking past and away.

I am confused whether I should be doing something, i.e. because they're actually walking away. Am I supposed to follow them? Should I stop them (e.g. grab their arm) after they touch me and somehow get them to abandon where-ever they were going? Or is it just communication, them saying "Hey! I Like you! You're cool!" but the same way I might give a guy (I'm a guy) a thumbs-up -- if a guy gets a thumbs-up from me he's not supposed to do something (like come over), it doesn't lead to anything else. Is this how I should interpret a girl purposefully touching me as she walks somewhere else (without any slowing down or anything like it)? Just general approval?

Alternatively, perhaps they would expect me to dance my way to wherever they ended up walking to? Is this what I'm supposed to do?

I basically don't know how to handle this. I just straight-up ignore it. (Or pretend to have disdain, because in this case other girls in my vicinity can secretly be watching me and see me reject some random girl touching me, which makes me seem more valuable - as opposed to if I suddenly look thirsty after the girl who had just walked past, which seems low-value.)

but other than ignoring it, I haven't done anything else. what should I do? (if anything)?

assume I am asking about girls I'm very attracted to.
