Years ago I found out the hard way there's an Ontario in California. Was chatting with this chick and she said she's "from Ontario" and I thought that was cool, so we started to talk about Ontario and after 30 seconds or so we were looking at each other like we had two heads apiece.
I don't know if you have a Japanese wife, or if so what area of Japan she's from, but mine keeps her food-play and her bed-play separate.
Which is a very good thing, because 2 nights ago it wasn't squid in the fridge; it was eels.
