Why is something so simple as eating with chopsticks viewed as showing off?

We ordered Chinese at work today, and I got sweet and sour chicken, so I decided to use chopsticks. I could use the practice… lol.

I was teased a little bit for showing off. Not in any kind of malicious way of course, but in every joke, there’s a little bit of truth.

So why is me using chopsticks showing off?
