Having a friend for a visit means we get to explain the eccentricities we take for granted.
The first time I visited my in-laws I was surprised to find out that the dishwasher was never used. Not even after a big dinner when it would have been filled to capacity. I found out since that hardly any Korean women use the dishwasher. The common belief is that it just doesn’t get the dishes clean enough.
Now, anyone who knows me knows I’m not a particularly clean person. Organized, sure, but as my Dad always said, “We don’t believe in the germ theory anyway.” Dishwasher clean is fine for me. However, when it's just the two of us, it's easier and faster to just hand wash and dry the dishes Asian style. On the other hand, when we make a big meal with lots of prep dishes, it's easier to fill up the dishwasher and run it.
A common question in our house is, “Honey, is the dishwasher white or Asian today?”
