The Conundrum

Happy times on the morning slog.  A fawn with the white dots ran out in front of me on the sidewalk and ran along with me for awhile before dodging back into the brush.  Then later I saw a pillbug creeping along the same sidewalk.

But here's the conundrum.  3 times I've seen a rat in my driveway this week.  But I didn't see him today so I'm wondering if the rat has moved on and maybe I'll never see that rat again if I don't dwell on its existence.
