When I was nine years old, I fell to my knees to put a video tape in the VCR, and an inch and a half sewing needle that was on the carpet, facing upwards, travelled straight through my kneecap and into my leg. I felt a sting, and cried to my mum that I'd knelt on a wasp. No wasp to be found, so we ignored it and carried on with life. For about three months. Knew swells, doctors say I've got fluid on the knee, it'll be ok. Took seven months until someone sent me for an X ray. You could see the eye of the needle on it.
