My MIL is a very generous and welcoming woman. Noni was in heaven because my DD came back from college, AND DD brought her roommate with her for a day or two, AND she wanted to introduce Roommate Emily to the grandparents.
So MIL made all sorts of food, and gave Roommate Emily an envelope with some money in it as a gift.
Roommate Emily was a wonderful guest--such nice manners!
Then after the dishes had all been cleared away, my MIL (who had warned me about it before) said, "There's one thing. The first time you're a guest in this house, you have to do the dishes."
Roommate Emily said, "All right," and got up gamely to follow my MIL into the kitchen. My husband was saying, "Oh, really, Mom," and his mother said, "No, they all have to do it!"
And she asked, "Do you need gloves?" Roommate Emily said, "No, I don't think so."
And my MIL said, "Good."
Then she pointed to the already-loaded dishwasher and said, "OK. Now push this button here first, and then that button next."
She's pretty funny sometimes, my MIL!
So Roommate Emily has been initiated into the close family circle. Next time, she won't have to push any buttons.
