ViceVersa
Everyone does it - even the Queen! I have no problem with it at all - and we have no locks on our bathroom door either (took them off when the children were very little after our niece managed to lock herself in her own bathroom and the door had to be broken down). As for the farting, you really wouldn't want to live in our house - between me with my IBS/DD, husband who could win Olympic medals if it were a sport and the dog, you'd definitely be clutching those pearls!
Everyone does it
ViceVersa I remember some advice given to me by an older colleague when I was in my first job, that if anyone intimidated you, just look at them while they're talking and imagine them sitting on the lavatory. Everyone has to do it, they're no different, she said.
