We had a friend visiting last week and dh was in the shower with the door locked, we normally leave doors open but cos my friend was here he locked it and ds started banging on the door saying "open the f*ing door." Naturally I was mortified and said to him that we don't say things like that but tried not to make such a big issue out of it, he just laughed and ran off.
Has anyone any words of wisdom to offer if this keeps happening??
