I just slipped while using one of my wedding-gift Wusthof knives, which we keep sinfully sharp, and managed to slice off a little chunk of my thumb and leave a big ugly flap hanging from my index finger. Now, I know by the amount of blood, and by sheer reason, that this is a fairly limited injury, but in my mind my finger is the size of a cucumber and that cut goes half way through it. Why is this?
I suspect this is a similar phenomenon to anorexic girls who draw themselves fat, or the reasons people imagine their pimples to be enormous and redder than they are. The play Copenhagen, which Sig hates but I love, has a brilliant line about how strange it is that the only person you can never see is yourself.
