We married late, which perhaps made it easier to decide who does what with regards to housework etc.
I made it clear from the start that I do not in any circumstances do any repairs that necessitate using power-tools, hammers or screws, nor do I repair or service bicycles.
I would happily continue doing the washing and do it for both of us, clean the flat properly once a week, but would appreciate help tidying up the things that have to be put away before cleaning, or when we know visitors are coming.
I would also gladly continue to cook, and as DH cooks as well, we could take it in turn, neither interfering when the other is cooking.
Cleaning the cat tray, decorating the Christmas tree and putting the decorations away are my jobs.
Carpentry, putting up shelves, repairing electric items, re-hanging doors are his jobs. I will help if asked to and told precisely what help is needed- making comments such as "just hold this will you" is no good. I want to know what "this" is, how heavy it is , and where I am to hold it before embarking on the project. I am not a mind-reader when it comes to household repairs!
I try to be just as explicit when I ask for help "will you help me fold this sheet lengthwise down the middle, please?" rather than "I need help folding this" - the kind of remark which tends automatically to make me say as my father would have done, "Well, you may, but what has that to do with me? If you need help, ask for it politely."
On the rare occasions DH has helped hang out washing, I didn't comment on how it was done, as I have known since I was a child of six that every woman in the world has her own system, based on that of whoever taught her to hang out washing.
Formerly, DH hoovered floors and I washed them - nowadays his back is too bad, so I do both and what I don't get round to doesn't get done.
