I've waited for this holiday all year. Kids have been so excited. We've brought my widowed DM - otherwise she complains she never gets a holiday and I feel guilty. She's great in small doses. I always forget how hard work she is any longer term. After a couple of days she brings a spikey atmosphere to everything. It's like having another child, possibly a sulky teenager. We are self-catering and she asks what's for each meal, never cooks or cleans up. If I suggest she makes any contribution to the workload it becomes an argument, or she asks for advice every two minutes. AIBU to say never again every year, and then give in and do it again?
