I had a situation once where I was in a taxi after a night out and a friend of mine came into the car, we were both drunk but she just would not stop trying to kiss me, grabbing me all that, kept demanding I came back to her house but denied it and went home. Both me and the cab driver just laughed it off, but looking back I did think "That was not ok, if the tables were turned I'd beat getting my arse kicked by that same cab driver"
The girl text me the next day saying "sorry, i'm bi-polar and was having some crazy medication trip" Funnily enough the same girl is now the biggest feminist/womens right activist on my facebook so whenever she shares stuff about rape culture etc. it does piss me off.
*edit* I actually still have the message and she says and I quote "Sorry I tried to rape you"

incredible.
