You seem to be called for jury duty a lot!

I'm glad that your brother's school problems are just typical teenage stuff and not anything horrible. It's not uncommon for some kids to purposefully hold themselves back, especially if they believe it'll keep them in high regard with someone else or not be teased by other kids or something like that. And at that age, you really don't think about how bad grades may affect you in the future. I hope he gets the message!
