HAT RACK, of course!
I may even have known that at one time. But indoctrination at an early age has a tendency to resurface. When you're six years old and you have only one sibling, and she's five years, six months and seven days older than you, and she tells you that it's "half rag", and explains that if you divide a square wash rag in two diagonally you get a triangular piece that looks like a Christmas tree - you have one of two options: 1) Believe 2) Get the holy crap knocked out of you. Needless to say, I sang "half rag" - and believed.
I'll have to call my sister and let her know how wrong she was all those years ago, but I'm sure it won't help. I may be fifty seven now, but she's still five years, six months and seven days older than I am. She can no longer beat the crap out of me, but she can retreat to the ultimate and unassailable older sibling argument: "I never said that, you must have dreamed it".
