I do most of the housework and cooking, and Mr. A works. He also helps me carry heavy shopping (I save the big stuff for him) and deals with the rubbish a lot. When he visited in the States, he took out ALL the rubbish, but he can't always be around to take it when it needs to go here.
We've made a lot of deals when it comes to getting things done and delegating duties. We generally take turns making drinks. We used to take turns picking films, but usually he now lets me pick a stack and he chooses within it.
One of the funniest deals was when he was visiting me during our LDR. He was there for 3 months, and I was starting to stress that we were spending too much time apart playing games. We each had a separate game we played online, sometimes for hours on end. So we bet each other we couldn't go 2 weeks without playing. The reward for winning would be a 30 minute "proper" backrub from the other. We drew up a contract and everything. We both got our backrubs. I ran across the contract when I was moving. So funny (in legalese).
