DH has a bad back. This is genuine (his work involves pulling large amounts of heavy metal about.) he said it was bad on Thursday afternoon but still managed to both make it into work Friday and go out for a few drinks with his mates so it wasn't bad enough that he couldn't move. He gets the lie-in Saturday, I get Sunday. So Saturday he sleeps until about 9 then gets up to drink coffee/go to the toilet/potter about before going back to lie in bed with the TV on. No visible indication that he was in too much pain to be able to move about normally. DD goes to an art/craft class thing Saturday so we left, leaving him a further three hours to sleep. When we returned at 12.30 he was still asleep. DD went for a nap so he had a further hour and a half. When he finally surfaced at 2 I was up to my eyes making a late lunch for DD. I asked him if he could change her and wash her hands before lunch and he refused on the grounds that his back was too painfu (he normally is pretty good about sharing nappy duties.) I lost my rag and he has been in a major sulk, saying I don't understand how physical his work is. Was I BU to have told him he was being pathetic? I don't get particularly bad backs but surely to be painful enough not to be able to change a nappy you would have to be flat on your back?
