I can't start a fire with slightly damp logs that anybody else in the world could get lit. It goes back to a weekend camping trip in my youth, taken alone with a lady friend where I spent at least an hour trying to make a small campfire, just to prove some ridiculous masculine point to her and myself. Both now and then, the shame in not being able to make fire is horribly real. Better still, this incident was only the first of many times I've disappointed a girl in the woods, with no innuendo needed or intended.
Actually, I'm changing my answer to camping in general. I'm just plain lousy at camping, although I suppose I'm incredibly adept at waking up with my head and/or feet in a puddle.
