Not only at Christmas, but if I'm pressed or time and I ask DH to do a job- e.g. peel the potatoes- it's probably because that task is time critical for getting everything on the table and hot at the same time and I'm doing three other tasks that are all equally urgent.
But he just adds it to his list of things to do, so if he was planning on feeding the cat/ sweeping the floor/ plumping the cushions he will first go off to do that task, so I then have to chase him to say that I appreciate cats need feeding and floor needs sweeping but can you just get the potatoes done first so I can then chop and get them on the boil, whilst I'm busy whisking the cheese sauce and basting the goose and wrapping the pigs in blankets all at once.
Then he will then think that he is project management for potato peeling and start delegating to me as his assistant.
"Of course. Can you get the potato peeler out? Which potatoes should I use? Where are the potatoes? Could you get me a chopping board? Please can you clear me some worktop space to do it?"
No my love, I want you to peel the potatoes and do all the associated work, including gathering the equipment and the ingredients and finding a space to do it in, I have asked you to do this not because I cannot peel a potato but because I need potatoes peeled right now and do not have any spare hands to participate.
Inevitably, I usually end up peeling the bloody potatoes. At least he actually is sweeping the floor and feeding the cats and not sat doom scrolling on his phone, but he doesn't understand the concept of prioritisation.
