The other day I made this exact point to Hubby by being rather direct, after all, we were standing in the kitchen and no one was within listening distance.
I said: Your zipper is down.
Hubby looked down, patted his zipper and said: Cheer up, chap! It can't be that bad! Poor guy. Things will get better if you have a cheery outlook...at which point, we both started giggling.
Life is not boring at our house.
