"Christmas Day:
“Do you need any help?”
Well, 4 hours ago when the veggies needed peeling, the table laid, the pets fed, the dishwasher emptying - yes please - but it’s a bit late now as I’m carrying the roast turkey and trimmings to the table!"
Yes, yes, yes to this! My mum sat downstairs on Christmas Eve waiting for me and DH to finish work at 5pm. Then sat and watched us make stuffing, profiteroles, gravy, peel all the veg... We were knackered after a long week, and she didn't even put the bloody kettle on for us, I had to make her cups of tea! I asked her to peel potatoes but they were muddy and she doesn't know how to use our peeler 
This is completely expected though, it's always been this way. She gives cash to us every Christmas which, in her mind, buys her a festive, full board break at our house.
I love her and I know when we arrange her visit that she'll never be willing to get stuck in with anything, so I put up with it because one day I'll miss having to turn my back and mouth terrible things to the ceiling.
