In a marriage each person does what he/she wants within reason.  My wife likes to do the laundry so she does the laundry.  I am driven to make sure we get at least one good meal a day so I do most of the cooking.

She balances the checkbook to the penny.  I never liked doing that so I certainly do not mind.  I stopped even writing in it for I would make small errors in it posting figures and when we got our monthly statement it would take her hours to find the errors.

There are some things I do for she simply won’t do them.  I empty and put new litter in the cat litter boxes.  I do the shopping.  I am not sure why but every time she goes with me we spend too much money.  Besides, she does not like to shop.

I do not like to clean.  She does just about all of it.  I do vacuum occasionally.  I could go on and on.  A couple divides the tasks as much as possible along the lines of what you want to do.

Of course, there are always tasks neither like doing and one person just decides to do them.
