Dear Brazilian Young Women program,
Hi there! As you are well aware, my 17-year-old brother is in town. He got here this morning - but, silly me, you knew this. You've been marking down the days on your calendars.
Let me emphasize something: HE DOESN'T SPEAK PORTUGUESE. And your limited skills in English won't get you far. In fact, even if you could speak fluently, he will surely run away if you approach him breathlessly with, "You are bewtiful verrry much! Kiz me! I love you!" It's just not a tactic American boys are familiar with.
