I can sleep anywhere regardless of noise, and i can fall asleep in seconds, none of this tossing and turning to go to sleep business i put my head down and i'm gone.
the noise thing is because i'm from wythenshawe and the sound of gunshots at night... hehe no its the planes, being so close the the airport and under the flight path the houses rumble and shake. it actually helps me sleep when i'm staying at my nans.
toilets, honestly i thought i was the only one who couldn't use a urinal when there's others in there. i have to use a stall or i just can't go. you cannot believe how good it feels to know i'm not the only one. i used to sleep with the window open 24/7 even in the dead of winter but my wife put a stop to that sharpish as she's cold blooded 
i also sing to myself regularly, i could be in the middle of a highstreet and singing and people will be looking at me well weird but its just something i do.
He who asks a question may look stupid for 5 minutes but he who doesn’t ask will be stupid for the rest of his life
