My friend's DS visits us fairly often. Whenever he has used the bathroom we discover the seat, unraised, and with piss liberally sprayed all over it and the floor. Nor does he ever flush, even after a poo. AIBU to think that this is poor form? Or is my friend BU in not teaching her child bathroom etiquette? The child is intelligent and tall enough to reach everything, no SN. He looks blank when we have gently pointed it out.
