He announced yesterday that we're having a Sunday roast today and bought a joint of slow cook beef, that translates to "you're cooking the Sunday roast" because he works nights then goes to football after his shift so it's all left to me to fuck about with meaning I'm stuck indoors all day keeping an eye on the meat.
He comes in from work has a quick shower and I say I really can't be bothered doing a roast today. He decides to be 'helpful' by plonking the joint of beef in the oven on the defrost setting without removing any packaging at all but not before wrapping it in additional tin foil?!
This is supposed to help me by taking away some of the work 
He sods off to football and after half an hour I have a feeling to go and check on the meat and find the abomination that is his attempt to prep it for defrosting.
I've got to remove it from the oven, remove the layers of tin foil, cut off all the netting and scrape off the paper base of the packaging which was now stuck to the meat like superglue.
I need to go to the shops today and get pack up stuff for nursery, do washing and other housework, look after two toddlers and now have the hindrance of this to add to my never ending to do list.
When he gets in from football he'll be going straight to bed, understandably, but I'm pissed off that he's managed to spoil my day by committing me to babysit a joint of beef I didn't want or ask for in the first place.
It's going to take hours to defrost and then hours to cook and I just can't be arsed with it all.
It's my time of the month so I am a bit hormonal, but am i being unreasonable ?
