We live in a strange old world. A world with flashing traffic lights and glass windows and ticking clocks and simple light-switches and extended noun phrases. All these inventions, bizarre when viewed objectively, but that help us get by in day to day life. Not everything is so useful, though. Traffic lights control transport, windows regulate heat, clocks keep the time, light-switches make it easier to see what you're doing. But is there any real need for make-up, for art, for puzzles and posters? Well, art and posters are for enjoyment and viewing, and make-up to make you look "nice", and puzzles to challenge your mind, but there's no inherent need for them. We could survive without them for sure.
But that doesn't mean people won't still play the necessity card when they hear about someone cross-dressing.
