Anyone ever had friends over that ask to use the toilet, yet when directed to the bathroom afterwards they tell you 'oh no it's fine' ...and just continue on with the conversation? It's a bit awkward to really insist, isn't it? Especially if others are present.

Have you been to a good friend or family member's house and seen something completely unhygienic, yet thought it best not to say anything out of politeness?

If so, does this alter the way you thought this person lives?
