Ah, but we don't all have your experience, Ricardian .... Only kidding, I was an in-patient at a military hospital when a four-stripe - and subsequently two star - friend came to visit me and brought the main ward to a standstill when he came in wearing a raincoat with his trousers rolled-up out of sight - until he "revealed" himself!
