A couple of weeks ago, whilst ds1 was up here on holiday, I went all out and made a lasagne - I have been on a diet, so have been avoiding things with rich sauces, plus it takes ages to make, and uses so many pans that I generally can't be arsed.
Anyhow, we all enjoyed it that evening, and there was enough left to do two small portions for lunch the next day - and as I hadn't had lasagne for ages, I was really, really looking forward to this treat - but dh and ds2 decided to have it for breakfast!!! I could have cried.
Then there was the Great Cold Goose Tantrum. I plan the meals, and had planned carefully for Christmas week - roast goose with all the trimmings on Christmas Day, cold gammon (cooked and glazed on Christmas Eve) with baked potatoes on Boxing day, and on the 27th, I was going to marinate the leftover shredded goose in soy sauce, runny honey and five spice then dry fry until sticky and serve with rice - it was going to be gorgeous.
Only when I got to the fridge, on the evening of the 27th, to get the goose out and start cooking, half of it was gone! It transpired that ds2 had decided to have a delicious cold roast goose sandwich for his lunch, and hadn't thought to ask if this was OK.
I am somewhat ashamed to say that I had an almost complete tantrum - tears, shouting, snot - the works. I stopped short of throwing myself on the floor and kicking my heels - but only just!! Dh had to lead me away to the front room, and ply me with gin to calm me down, otherwise I would have killed ds2 in his actual face.
Of course, it was all completely unnecessary - we had a house full of food, and dh was able to put together a lovely salad with some cold roast goose and cold gammon - I can only assume that it was the cumulative effect of the stress of organising all the presents, decorations and food that made me revert to the Toddler from Hell. 
This was several years ago, and it is still brought up every year by the family. It wouldn't be Christmas if someone (or more than one person) didn't suggest a nice cold roast goose sandwich, at some point over the holiday. They do it from out of reach though!!
