areyoukidding: "I'm short, no wait a minute, i'm long, no no, that's not right, i'm short, er no, i'm long, ah no, i'm flat, with longs, wait, wait, i'm short-long, oops, i meant i'm long-short, no no i'm short flat long, oh sorry, now i'm flat long short" and so on, and so on. Your 20-20 hindsight is perfect.
