I was coming home from work on the train, I was tired, I was reading a very interesting book, and . . .
The unthinkable happened.
I missed my stop.
I had completely forgotten I was on a Green Line train, and would therefore have to get off at 21st and switch to a Red Line (unlike the Blue Line, which goes straight on through; have I mentioned them all yet?). Then, Little Miss Matter-of-Fact's voice said "Next Station, River Trail, 11th West," and I knew.
It took me a little longer than usual to get home today. Ach. I needed a change of scene.
