On a point of elucidation, my family doesn't object when I read in the bathroom. And there are only mild mutterings if I take in the mandolin or guitar.

But there's a near riot if I spend my time in there practising the trombone. I maintain that the bathroom is an area where unwelcome, involuntary noises are frequent, and a trombone is a legitimate cover for such activities.

Especially in these days of thin sidewalls. A female companion and I had a rough time on a visit to the States where we stayed at people's homes after long car trips. Companion was reduced to flushing first, turning on all taps, and singing loudly while trying to evacuate hurriedly.

A trombone would have eliminated that problem and I suggest that there should be one in every bathroom. Would this be a widely held position?
