We live in a very popular seaside town and have a self-contained annexe. We use it as a WFH space when not in the office and it's useful for close family to stay in. This year we've had two different sets of guests come to stay and both times they've stayed much longer than I expected (a month and two weeks). The last guest didn't even leave a bottle of wine/chocs to say thanks. Nothing. I'm expecting another request to stay soon and I just don't want to do it any more. Am I being a grump?
