Bilingual cartoonist MandMX explains the 13 stages of using chopsticks:
I learned how to use chopsticks when I spent a summer working as an intern in Hong Kong in 1979. On my first day I joined some of my local co-workers at a restaurant. I told them I didn't know how to use chopsticks. "When you get hungry enough, you'll learn," they said.
I think it took me about 5 minutes.
By the way, this cartoonist has been known to use my 'tweets' as inspiration for a cartoon: "My Life as a Cartoon."
