Totally get this! We are having a week of family time, including the far flung contingent, totalling 15: endless catering, dishwasher, table laying and clearing.. It's wonderful, but when they all go I will enjoy a recovery week of bread and cheese, possibly eaten from the bread board to save on plates.
I do understand that. Sometimes I look back and think that I produced 3 meals a day for 5 people over decades - how the hell did I do that? I now eat the same few meals on a cycle as I am all cooked out.
It just all gets sooooo boring. I mean I really just cba sometimes and that goes for eating too so why do we have to be worried about everyone else too!
I often make a meal that's enough for three (there's just two of us), then I ask OH if he's happy to have it a second day, he know if he asks what else is there, I'll just say "nothing". I'm happy with cheese, fruit and crispbreads.
