She is yet to find out what blood type she is and we are always guessing. She thinks she is B and I think she is AB according to her personality. I'm B, hubby is AB, so another possibility is for her to be A... but if she is, she doesn't fit the profile.

OMG -- I'd forgotten about that weird Japanese blood type = personality thing. I used to work for the Japanese Consulate in Montreal, and the diplomats were always so surprised that so many Canadians have no idea what their blood type is, and I couldn't understand why anyone would necessarily know (or care) what their blood type was. Until I learned that it's basically the Japanese equivalent of a Myers-Briggs thing.
