Hmm... Well, motive's about the only thing I can think of. There's no reason for me to whip up such an elaborate lie and tell it to someone I don't even know. That's rude, unseemly, and just plain mean.

And if I've got false memories, even I wouldn't know. We'd both be better off making sure I'm not full of shit. Me so I stop looking like an idiot, and you to see whether or not you really do need to hightail it back to... Japan, was it?
