I used to tell my wife we would be having a "conversation."
For a while, we had a spending rule. We both work, my wife even earns a little bit more than I do, but we put all of the money in the same account, we don't have "my money" and "her money." But under the rule, my wife could spend up to a certain amount without consulting me. But if she spent more without talking to me first, she went over my lap that evening. As she was heading out to shop, I would remind her that we would be having a conversation if she spent too much. (I would also talk to her before making a significant purchase. Fair is fair.)
Sigh. I really liked that rule. I generally don't have a lot I want to buy. My wife likes to buy things fairly regularly. Not super expensive, but enough so if we both did it, we would feel it a little, financially. Taking her over my lap when she spent more than "x" not only reduced the times that happened without making her feel resentful about not getting what she wanted, it also kept me from feeling jealous that she was spending more on stuff than I was.
And, of course, it was pleasant to think about her there at the store, deciding whether to go ahead with a purchase that would exceed the rule . . .
She knew that that evening she would be lying across my lap, with the purchased item in view for her contemplate whilst we had said conversation . . .
Hmm, I have gone off into "hijack the thread" territory on this one. So back to terms: "conversation" if anyone is around, "lap time" if it is just the two of us.
