This is one of the dumbest threads ever and me responding to it makes me even dumber I suppose. Off hand, I would say it's the drugs maybe.
The mind halucinates.
When my mother was in the hospital and they were giving her pain killers, she would say things like, "the donkey is in the coner", and "we're all going to eat cake" whle being in a drug induced sleep. Do you think that that meant something? Was she secretly fantasizing about having sex with a donkey, or worse yet, whilst eating cake?
If you're going to call it quits with your GF over something so silly, she's better off alone. People are entitled to their thoughts.
