Wow, so the newbies are leaving today and tomorrow for staging, how exciting! I wish you all the best of luck! Seriously, its going to be an amazing experience, in any case. Even if you have a horrible time, its an experience. I had pretty much the worst experience one could have short of dying, and I can still think about it in positive ways. I even miss the 'desh at times. Just remember to laugh a lot, but never let your guard all the way down. Trust no one, not even in your host family. If you ever have any incidents--report them! And keep track of everything on your own--things you report, incidents, even illnesses. Don't trust the office to do it accurately.
Ok, enough of the serious stuff, just try to have some fun. You are going to meet some of the most amazing people in your group--you all have such interesting and varied backgrounds. Your training group becomes your family-be good to each other. And have fun w/the B7's, they are all really cool and will help you out a lot! Email or post anytime!
