It depends what im eating, who im eating with, etc. Sometimes certain things are easier to eat with chopsticks. Other times im fine with a fork or spoon.
At home I usually eat with a fork cuz my family does...but if I feel like it I'll get my chopsticks. I don't have the throw away kind though O.o I have to wash mine(but I have like 5 sets of them).
If I go out to a Korean restaurant(or any Asian restaurant) or with my friends I use chopsticks.
