I'm always doing this!!
For instance, last night I served up sausages, bubble & squeak, swede and carrot mashed and gravy. When we'd finished I then remember there's a panful of sweetcorn on the cooker!

I'm always doing it. On Sunday I sat down to eat my dinner; about fifteen minutes in (it sounds a lot but I'm a VERY slow eater ) I realised I'd left the stuffing in the oven.

I don't think so, but I've probably forgotten.

When we sat down to Christmas dinner, I did remember that I had got parsnips especially...and completely forgotten to cook them.

All the time I also missed the sweetcorn last night, I'd popped it in the microwave at the last minute and not only had I forgotton about it I had cooked it for too long and had to spend a few mins picking out bits that had popped out the jug

I remembered last friday while shopping, I'd bought all the ingredients to make bread sauce on christmas day to go with the turkey. The thing is I knew there was something missing, just couldn't think what only took 2 weeks to remember.

Made the cranberry sauce, put it in a fancy dish, forgot to put it on the table on Christmas day, I always forget something, my head if it was'nt screwed on.

I'm always forgetting to put garlic bread in oven!
Or else I'll make nice salad and leave it in the fridge!

My Mum cooked a huge roast one time and got herself in to a right flap, everybody ate their meal and made the right noises but after she had left the room my sister asked "Weren't there supposed to be potaoes with this?" it took around two hours to locate the roast potatoes which were shoved at the very back of the oven, we havent let her forget it!

We've forgotten to cook the stuffing on Xmas day two years running now. No one seemed particularly bothered though.
