Settle a not-very-contentious argument between me and DP.
I think that once sheets have been taken off the bed, washed and dried, they should be aired, and the bed remade with the other set of sheets. Then the aired ones go back on the following week.
DP thinks you can take them off, wash and dry them and put them straight back on the bed, so that the other set of sheets just sits forlornly in the sheets basket forever.
YANBU - of course sheets need to be aired for a week and the other set used, only a barbarian would think otherwise.
YABU - why waste energy folding sheets when you could just put them straight back on the bed toasty warm from the dryer?
