Ten years ago or so, back when I still needed glasses, I stumbled out of bed, put on my glasses, and headed to the bathroom. I was very tired, so I sat down to pee. Moments later, I fell asleep, toppled sideway, and smashed into the tub. My head hurt like hell, my glasses were seriously bent, but I just crawled back to bed.
In the morning, I fixed my glasses and took a Tylenol.
A few years later I started getting nosebleeds. They became frequent enough that I, an immortal man, called my doctor. I was sent to a specialist, who probed unpleasantly and said "Looks like you had an injury and have a deviated septum. Did somebody punch you in the nose?"
Well, if a bathtub can be somebody, I guess so.
