I can't sleep.
My brother and I were discussing individual quirks in ourselves and ones we'd notice in others.
I chew the inside of my mouth. Not because I am hungry, it's probably some boredom defelctor that I created when I was little. Been doing it for years.
My brother divulged to me that when he has a poo and he wipes his bum he looks at it (the mangled, soiled tissue, that is) before he flushes it down.
Then I rembered one of my ex flatmates used to put SALT on her bacon when she was frying it up, and another friend of mine FREAKED out whenever someone put their toothbrush in the same cup on the sink, even though there was only one cup.
