I also eat my food in groups.
Before doing the dishes, I stack them the way they would be stacked to dry, and wash... I try to explain to DH that this is so I don't have to find a place for things as I grab them... like he does so there is a higgledy-piggledy unbalanced mass of dishes which could topple at any moment. Mine is neat and dries fast.
Have to iron shirts first.
I rearrange my books every 3 months- and on the second time, they go back to the way they were when I first had enough books to organise (basic A-Z). But every 3 months I organise them differently (split categories A-Z, genre A-Z, etc).
I don't sweep unless I am going to mop too- why bother.
