I've just found a downside to bellows piping I had not expected. I was practising just the other day when the door bell interupted. I slipped my pipes from the bellow and opened the door to find a neighbour and a policeman seeking information on an opportunistic burglery next door. I could not understand the cop's rather aggressive attitude until a couple of days later when talking to my neighbour, he had asked her why I was wearing a shoulder holster!

I can only thank my lucky stars our cops aren't routinely armed and that I wasn't carrying a table leg...
