A guy comes home from work and says to his wife “Lets fuck”.
She says “That is very crude. When you are “in the mood” just say “Let’s do the laundry”.
“Okay” he says “lets do the laundry”
She says “I can’t now, I’m going to get my hair done”

Next day he comes home and says “Let’s do the laundry”
She says “not today, I have a headache”

He stops talking about the laundry.
After several weeks go by SHE is “in the mood”.
When he comes home from work that day she says “lets do the laundry”
He says ” I only had a small load so I did it by hand”
