Oh, I sulk..... probably BIG time!
It's usually when I have a 'good idea' that Andy won't go along with... I can see it's the best idea in the world, that it WILL work, it WILL save us money (in the long, long, run

) and he still refuses to play....
So, I stomp - I bark one word answers at him, I ask him if he wants coffee/sandwich/anything from the shop, but I purposefully don't make eye contact when I talk to him....
After a while, usually an hour or two, he aks me to explain my idea again to him.... and then he gives in...sulks over!!
Actually, thinking about it, there haven't been that many sulks, and the vast majority of my ideas have turned out for the best - ok, a few of them haven't, but so far, no harm done!
However, if we have a falling out over something that ends up with a row & it's really HIS fault, I handle my sulks by jumping in the car & going off without a word.... whatever the time of day or night (ok, thank goodness for 24hour T***o!) then I buy something naughty-like, chocolate, cream cake, new undies, whatever, and drive back home again to lock myself away for a few hours - after which he'll apologise & that's the end of that!
