Dear Arizona,
   When I found out my friend would be playing a trumpet solo at our school’s band concert, I was so jealous that I couldn’t even talk to him. How can I go back to acting normal again?

Dear Envious,
   Your letter reminds me of something that happened with me and my friend Mareya Becker, who’s incredibly good at karate. When I think about the way I acted, I get so embarrassed! But everybody makes mistakes once in a while, right?
