Whose undergarment Are These???

A wife goes on a retreat for work for a few days.

When she returns and enters the house, she puts her things away and then goes to do some much needed laundry.

Upon her entry to the room, however, she finds a pair of undergarment on the floor that do not belong to her! Furious, she questions her husband.

The husband says, “I have no idea where they came from I don’t do the laundry, the maid does!” The wife calms down and says, “Oh! So maybe these belong to the maid, could be she was doing her laundry here.”

“Nah,” said the husband musingly, “she doesn’t even wear undergarment.”
