Somewhere there is a very sleepy mouse...

I keep a half of a sleeping pill next to my pillow at night, just in case.

Last night when I went to bed I kept feeling a mouse run over my lower legs and occasionally under the covers.  I eventually fell asleep, and when I woke up this morning this was all that was left of the sleeping pill near my pillow...

With the hot weather coming and the increasing familiarity with the mice, I believe it's time to start sleeping in the garage...
