Same. My wife and I have a shared bank account which our salaries go into and which our bills come out of. Neither of us are especially profligate so it works fine. We discuss any significant purchases, but don't worry about the small stuff, just check the budget through the month as we go. We never argue about money.
Our spaniel once got a thorn in his foot. My dad took the thorn out and our dog snapped at him. He then ran in little circles, snarling at himself for having snapped at my dad.
Flirting is all about observation and escalation. Flirting is a game of fun, it is not seduction. You do it to entertain and entice, not to get your end away.
You start with a comment, or joke, or double entendre. If your flirtee responds in kind then you progress and maybe escalate a little with another comment or joke or double entendre. What's most important, though is the observation. If your flirtee backs down then you fucking back down too. If your flirtee misses the cue then you back down. If you're not sure, you back down.
Hmm, perhaps this is the key. I sing a lot, in the car, or the shower, or when no-one is around, so I get practice in but I don't (can't) hear what I'm singing properly.
