Earthworm in the kitchen

Yesterday morning I was going thru the usual motions when I saw a crooked something on the kitchen floor that looked a little too regular to be a stick. It was a dirt-covered earthworm! I can only assume it came from the flower boxes we had brought into the kitchen the night before because the overnight temperature was supposed to get down to the freezing mark or lower. The compost I'd used with the potting soil often has worms in it, so I'm guessing my little visitor was an escapee. I escorted it outside to a nice little bush, where I hope it's much happier and aerating the soil there.
