Why do I hate that question? I find myself really rather annoyed when one of my kids comes into the kitchen while I'm cooking and asks me "What's for dinner?" I don't even have to be in a particularly bad mood but it just irks me. I know it's an innocent question and they just want to know but it just bothers me.
I think it has something to do with feeling some resentment about the possible reaction. Like it has to meet their approval. Sometimes if someone isn't crazy about the day's main dish or veggies or whatever, they'll voice that opinion and that bugs. Also it might also be related to feeling like I'm some kind of servant. Like, "What's on the menu today?"
The thing is, it doesn't bother me when E asks say on the phone on his way home. Probably because I know he's asking out of anticipation and never complains about the food. I guess it's just picky kids but I think I have a solution. I'm going to start writing what's for dinner on the white board that's in the kitchen and that will be all. I don't have to deal with the question and they have their curiosity satisfied. Hoping it works!
