The way I eat potato chips I don't remember from since I started to do this, but I've come to eat potato chips with the chopsticks and pick up potato chips from the packages. Of course I realize most people don't do this, but I just want to keep my fingers clean from the oil and the salt. At first it was a little awkward behavior to me。But at this point, I even can't think of using my hands to eat them. My sister used to always makes fun of me when I eat like this, but finally she started to do the same thing yesterday! From now on, this might be a new traditional for our family.
