In highschool, a girl I fancied asked if we could play the awkward game, where the point is to make the other person feel awkward and bail.
Well her first two moves were taking off her bra under her shirt, pulling it out through the neck, and throwing it at me, and then sitting on my lap facing me.
I still did not get the hint.
I found out a few years later when she was going off to college and we were chilling on the couch reminiscing. No chance by then though for either of us.
Remember, when you ask yourself "how could you not understand that", people like me exist.
