My theory is that 'he' is ctually a bit of a wuss, whilst 'she' clearly wears the trousers. 'He' decided that DIY was his last manly bastion and there is no way 'she' could beat him at this. Now unfortunately 'she' has beaten him, and 'he' has not one ounce of machismo left in his body. 'He' should give up trying, buy a little apron, and resign himself to the fact that 'he' is screwed.
Just my opinion though ;-)
