In Hayame's case, say something over the top and really lay it on thick. Like... [A pause while he thinks of the first thing to pop into his head,] "Hayame, stop making assumptions about me and being a big meanie! I wasn't trying to say that, and you're making me sad!"

Then you'll put her on the back hoof, and she'll be too busy huffing and puffing and being all confused to remember what you were even arguing about. Works like a charm.

[hit her with the ol bamboozle!!]
