1. You hug your wife from behind, she steps to one side and tenkans and ducks, escaping your hug - and you tell her, "That's good, love, but try lowering yourself a little more as your raise your arms."
2. This is standard romantic couple behavior for the two of you, along with her doing iriminage on you when you're feeling, um, playful and she's playing hard-to-get.
3. You already know that when you tell people you first met your wife in the dojo they will inevitably ask: "How do you guys fight?"

(seriously, do they really think of us as violent sociopaths or something?

). To which you reply, "What are you talking about? That's foreplay for us!"

Which earns you yet another strange look.
