That is quite true. Although everybody has peed in a place where a door was available at one time or another. Public stalls, and other peoples bathrooms for instance. Even at somebody elses house, if I'm comfortable with them I generally don't close the door.
sorry I didn't read anythink - my mate from deutchland used to roll a spliff - pass it on - wait for it to get back - announce he was going to the toilet and take his guitar - he'd go to the shitter and we'd listen to him playing the guitar.He'd come back and say how inferior he felt cos the only door for the cat was the toilet window - and if the cat heard him in there it would come and sit on the toilet window ledge and stare at him while he was playing/shittting.Best wishes Slim wherever you are - hopefully back in holland that you missed so much
