When there's a group of about 6 young males on the bike path and one of them says 'hi beautiful', do you...
A) ignore them, because what is telling them to f*** off going to achieve anyway?
B) tell them to f*** off, give them the finger when they respond, and then pissbolt out of there when you think you hear them call out 'get her' to the guy further ahead.
I really hope I misheard him, but they didn't have a hope in hell of keeping up with me. Must learn to control my response to casual sexism.
