Following the driving thread I just wondered how many people have tasks which they consider to be his or hers?
Both my partner and I had lived on our own for many years before living together so had to do all the jobs which means we both still do stuff as it needs doing without any 'that's my / your job'.
Obviously if there's something one of us is better at there's some wiggle room with this, but both of us are perfectly capable and willing to do anything which needs doing.
YABU - there are still traditional male / female jobs in our house
YANBU - anything goes, unless one partner has particular skills
