We had a maid barge in on us once, and it really was an inopportune moment, but I suppose that would depend on one's opinion and viewpoint. The DND sign was hanging on the door for a reason!, anyway she walked in right at the height when things were getting really energetic and a little loud(I'm a screamer ), my wife kinda freaked abit. Me? I was pissed off, she completely made us lose our rhythm. Had to start all over...well, maybe it wasn't so horrible
