Asked MIL if she could give me the recipe for a dish she cooks well (I share my recipes with her), she agreed and gave it to me - but with key ingredients missing so it wouldn't taste nice. Deliberately - she has past form for doing this. (When she did it before it was years ago and I'd forgotten about it until it happened again. )Don't you think that's really mean? By all means refuse or make an excuse, but to let me waste my time making something that's not going to work..? We've got small kids and work long hours so I particularly begrudge her wasting my time in this way. AIBU to be really irritated. She was due to be coming round for dinner this week and I honestly don't think I can bear to make her a nice meal and be civil to her!
