Picture the scene.
You have one day off work and spend it washing-up, putting away breakfast debris, cleaning, doing the washing and the ironing, shopping for food, gardening, matching up odd socks, picking up and tidying general discarded junk belonging to the rest of the family, emptying the bins, paying bills, bringing order from chaos in teen dd's room, recycling old newspapers, taking old books to the charity shop, fielding unwanted texts from people asking stupid questions about work (and who have forgotten it's your day off), watering the house plants, talking to MIL on phone, paying school trip bill, and figuring out the logistics of after-school club timetabling for the whole of the next term and beyond... oh yes, and cooking dinner.
DH arrives home from work, finds you on the sofa (where you have been in a state of collapse for 3 minutes) and says:
"So... what have you been doing all day then, while I've been at work?"
