I was at work today, and girl who i've been making friends with (not trying to pick her up, i think that shouldn't be in the work environment) came up to me and picked a hair off of my collar and held it up with a smile.
I said "HEY!" in a semi-serious loud tone, pinched my fingers together, grabbed the hair back, and slapped it abruptly back on to my collar and said "excuse ME!" in a very sarcastic CF tone and went back to doing my work
she laughed pretty hard and kino'ed me a bunch after that. I thought it was a great way in the future to react to her touching you like that
I think it would be FREEK'N GREAT if she takes an eyelash off of you, and you SLAP it back on to your face
heck, it's much better than saying "geeze, thanks....[bend over and say thank you some more]"
