MonoMonday: Escape

It was a hard theme today. 
Nevertheless I set off around town in the hope of seeing a police car in full pursuit or something when I came across this. 
I have never noticed it before. Maybe they have only just escaped. Or perhaps were in a hurry to get in.

It reminds me of the old joke:
Wife to naked lover: Quick, my husband's coming up the driveway.
Lover: Where's your back door?
Wife: We don't have one.
Lover: Where would you like one?

Thank you Ellaphant for hosting this month.
