Whether I should change myself?

I am a chinese student, in my life I use chopsticks to have my meals.
But I'm not like my most classmates using the chopsticks in right hand.
So I often "fight" with my classmates when I enjoy my food with them. I
feel very sorry. Now, I begin to avoid to stay with them when it's time for
meal. Maybe it's not serious in the campus. But someday, I enter the
society, what I should do to deal with the problem? That'sall , thank you!
