I work around 52 hours a week, sometimes much more. OH works 45 hours, so we share all duties. We get a monthly shop online, but pick up day-to-day pieces when needed. He'll do the obvious housework (washing up, hoovering, dusting etc) and I pick up on the things that males don't notice! I'm usually too tired once home from work, so I tend to get up early to get things done.
We both cook, and try to do enough to last two days (curry, chilli, lasagne etc are all still tasty the next day). I always do the roast on a Sunday and days like today when we are both completely knackered, we chucked pizza in the oven.
The dog gets an early morning run, an afternoon run and an evening walk. Who takes her is simply a question of who is home. We never talk about the housework, we seem to have an unspoken rule about who does what!
The only thing that winds me up.....when he picks up on one of my duties, like cleaning the toilet, he'll take great delight in letting me know that he cleaned the outside of the bowl as well as the inside. I resist telling him that's all part of cleaning the toilet, and go with 'well done', instead!
