Dear Abby: Host frustrated with lazy guests at dinner parties

Dear Abby: I host dinners for most holidays and birthdays for my relatives and friends. I have a relative and a friend who have enjoyable and shared interests, but every time they come, they announce that they do not cook — as if it is a badge of honor. I’m beginning to resent the comment after spending hours shopping, planning, and preparing the meal for everyone. When they do offer to contribute, they bring a tasteless pie or an item from a discount bargain store.
