I spent months learning how to use them properly in secret and finally deployed my skills when I thought I was pretty good. She didn’t notice. I then realized she almost always used a fork. In high school and college their meals were always served hastily and the students always brought a fork or spoon. they would eat standing up and had maybe five minutes to get the job done. No time for chopsticks.
When her parents came out to visit us after we got married I frantically asked her advice about good chopstick etiquette. I very much did not wish to cause her to lose face. She didn’t give a flying fuck. I honestly think I married one of the freest spirits in Asia, which is not necessarily a compliment.
She said I was doing fine and literally refused to give me any feedback at all, incorrectly claiming she wasn’t even that good. In fact, I think she only started to resume using chopsticks because I ended up finding them useful and now far prefer them to silverware.
I ended up having to learn most of the customs by watching people in restaurants. Just learning how to set them down right took additional months because I noticed far too late that they set their chopsticks down in a sort of V shape which is much harder than one might expect. Also, I am left-handed, but taught myself to do it right handed on the theory of that would also help me not lose face in front of the in-laws. It turns out they are also highly unconventional and probably didn’t care about my chopstick use one way or the other.
When we had kids, I would learn that Asian children who don’t learn to use chopsticks represent another way to lose face. It results in titanic power struggles within the family and makes everyone miserable. It’s a little like forcing kids here in the USA to eat their vegetables. By this time I had learned of her disinterest, so neither of us bothered to teach them. All of our children naturally picked it up with no apparent effort, including one who is very severely developmentally disabled.
