I genuinely not sure if I was being unreasonable or not. Just before Christmas my wife came home from work about 19:00 and said they were having a party at her work the next day and she said she would bring a cake. I said I'll pick one up at the supermarket when I go out. She said no, I want you to make one. (Some background, I enjoy baking and often make cakes and desserts). I said you didn't think to ask me before now, I've been at work all day and am tired. My wife didn't take it well and stormed off in a huff. I felt bad and made a cake. I was proud of the cake I made, it wasn't up to my usual standards. However, that wasn't from spite, it was just I was genuinely tired and I didn't get it finished until nearly midnight. Was I being unreasonable or not? I don't know whether I should have been pissed off with DW or not?
