Maybe I'm in the minority, but I always say thank you when someone cooks for me. I'm on maternity leave, so basically doing all of the cooking / cleaning/ washing / clearing up. DH can't even be arsed to put his stuff in the dishwasher, a classic pile it up the side of leave all over the house.
But the very least, surely, is when I've cooked him dinner he could at least look up from his phone and say thanks? I get that he's been at work, but am I asking too much?! Silently fuming and wondering whether to pick this fight.
YABU - You don't need to say thank you every single time someone cooks for you when you're off work anyway
YANBU - Doesn't take much to make me feel a little more appreciated and it's definitely good manners
