Dear Chris,
I can only hope that our time together was long enough for my extreme xenophobia to affect you. You are going to be traveling the world for a year, and you know how much I hate other countries. My only ask to you is that you constantly remind them how much better you, and by extension, your country, are when compared to them.
It also wouldn't hurt to throw a couple drunken "USA, USA," chants in there for Brandon. I'm sure that he would appreciate it.
Finally, I just want you to realize that you are going to miss a Lions Superbowl. Are you sure that you don't want to reconsider this trip? You still have five days.
Sincerely,
Your brother
