I have a lower clutter tolerance so I clean, but DH is ocd about dishwasher loading and laundry sorting and prefers to do both (first straight man I ever knew that reads and pays attention to care labels--and back off gals, he's mine!). He occasionally will make some smart remark about me "playing with dollhouses", though generally all I need to do to shut him up is ask how much he spent on comic books that week.
What can I say, we're both perpetual 9-year olds! :-)
