You forgot the fourth reason: B.O. Years ago a client that we call "Jabba the Hutt" came waddling into my office. Heidi got a sniff of him and immediately started howling. He looked at me in bewilderment and said in his British accent: "What in the Queen's name is disturbing Heidi this day?" I replied to him: "You do not know?" He replied: "Most certainly not my friend." I said to him: "Maybe that swarm of flies that followed you into my office is a hint."
