Santa really dirties his clothes visiting children young and old and Mrs. Claus cleans his suits for him. Santa can always count on a fresh suit when he makes his many trips visiting the boys and girls of the world.
Mrs. Claus does a lot of cooking and baking with so many elves living at the North Pole. Not to mention how Santa loves his cookies, pies, and cakes. But, Mrs. C always makes sure Santa eats some fruits and veggies...whether he wants to or not.
Santa sends and receives a lot of mail. Often there is a letter Santa needs to see immediately or a package that must be shipped. Mrs. Claus is the one who makes sure the mail is delivered.
