We have some friends, a family of 4, who have invited themselves over for lunch at the weekend. Just straight out, "how about we come to yours for lunch on Saturday" 😯 I see this as blatant CF'ery, DH doesn't think it's an issue. Not only have they invited themselves, they've also suggested that we invite some other mutual friends too! DH has already agreed to all of this, like a mug 😡. They live in a small flat so never host us, and I don't usually mind that, but it's manners to wait for an invitation!
