We see a lot of threads about what the partners do that grind our gears so I thought maybe some of us could own up to the things we know we do! No one is perfect after all 
I'll start... Mine is baths. I can sit in the bath for well over an hour which often leaves OH bursting for the loo or waiting for a wash himself. I'll admit, it's pretty selfish when he's come in from a day at the workshop very grubby and needing a clean. I don't even notice the time go, I just love relaxing in there!
