I hate it when the rug is flipped over at the corner or the blinds are up/down unevenly.
Dishwasher has to be stacked my way (i.e. properly!) or it gets re-stacked.
At the supermarket check-out I always put groceries on the belt thingie in order of where they go when they get home - all the cold stuff first, pantry stuff, fruit, veg etc. DH knows to go straight to bag and trolley duty when I'm doing this or I get really frustrated with his attempts to 'help'. It's the way my mum did it, it's the way I did it and I bet my daughter does it too!
