My little foible

On either side of our front door we have small windows with matching stained glass - primroses in case you can't tell from my brilliant sketch. The one on the left as you look at it is the window of the downstairs toilet.

In the evening when I use the downstairs toilet I don't put on the  light until I'm washing my hands. I'm not sure who I think is going to come to our front door late in the evening at the precise moment when my bottom might be a tiny bit visible through the frosted and stained glass and why that visitor would want to peer in through the window, but that's the way it is.

Do you have any little foibles?
