This is mother-in-law's day for me. This isn't a vent, it's just the way we've worked it out. We have the in-laws over for lunch and spend the afternoon together. I never think of it as my day. For the U.S. Mother's Day, I send my mom a card (with a long letter in it), and we go out to dinner or get a takeaway--or at any rate, I don't cook.
It's just a way of spreading around the honours.
