Pity I forgot about the second set of stairs.
So my foot went down where I didn't expect it, and I collapsed down on my foot.
Now one of the tendons or muscles or some such thing hurts, especially if I tried walking on it. Yes, doctor, I know I shouldn't walk on it, but what if I need to go to the bathroom or get a drink of water? Can I walk on it then?
That's one of the worst things about living alone, if you injure yourself or get really sick, you still have to take care of yourself.
