My mother, a nisei (Japanese American - born here), is totally a Guesser and it drives me crazy because I am not a mind reader. If I want anything, I can't ask; she has to bestow it on me. When I lived in Japan for a bit during college, I knew it was a guessing culture and I knew my language, incl. body language skills were too rudimentary to figure it all out.
IMHO, the U.S. is too diverse to be a guessing culture. I tend to be reticent and have a hard time being an Asker; cultural conditioning I suppose.
I am mixed on being a rice grower vs. wheat grower. I am okay with sticking out a bit, but I don't want to stick out too much. I've received many comments about having upped my style quotient (since joining YLF btw), but haven't yet received snarky comments from my mother which indicates that I haven't gone too far out on a limb.
