Since lockdown, DH and I are both working from home. Me at the bedroom desk and him at the dining table. It works well and we stay out of each other's hair most of the day. I've found myself growing more and more irritated by something that I thought was just common courtesy, and I want to know if I am being unreasonable.The bedroom where I work is right next to the kitchen, while the living room where he works is at the other end of the hall. Whenever I get up for a cup of tea or a snack or to make lunch, I walk down the hall and ask him if he would like some too. Growing up, it was considered the height of rudeness to prepare something for yourself without offering some to others at home, unless for some reason it would really put you out. I do this without a second thought. On the other hand, he walks right by my door and makes a snack or drink and never asks if I'd like any. He will even pop in the doorway with his tea or food to say hello and chat and see how my day is going, so its not like he is in a rush (and it doesnt take any extra time to take out two mugs and put double the water in the kettle). My work has been very intense and busy while he has, in his words, "f_-all to do" at the moment for his work, but I still always offer and he still doesn't. I suppose he wasn't raised that way, and I should not project that expectation on him, but it irritates the heck out of me nonetheless. Am I being unreasonable?
