Another thing that I read in one of those male/female books is about the difference in vision for men and women which supposedly stems from when we all lived in caves. Sounds dodgy but makes sense:
If we assume that most men are descended from the hunter/gatherer types, and we imagine them in diagram form, standing a way off from their prey, then we see that their vision has a very narrow range, i.e. just focused on their prey - or in modern terms, just focused on one thing: what they are doing at that very time.
If you compare this with the diagram for a woman and you imagine she's the one stuck in the cave with the baby, her vision is MUCH wider, as she needs to take in all of her surroundings and suss out the environment so that she and the baby are safe. Again, projected onto modern life, this is what we recognise as multi-tasking.
Women are much better at walking into a room and sussing out a multitude of situations: where's the exit, who's with whom, what kind of curtains are up, what food and drink is being offered, etc. Men walk into the same room and see what or who is in front of them, End Of (as the Big Brother contestants would say).
So, when you ask you dh to cook the tea, they will do just that - the kitchen will be a pigsty, they won't have put stuff away, the bin will still be overflowing but the food will be on the table, just as you asked!
All huge generalisations, of course, but you get the picture.
