Yes, Ladies and Gentlemen - - It's time, once again, for our favorite Soap Opera, "Castenets Time In Brazil"!!
This is really very simple.
You tell him, that in 1 month, you're both going on a "son/father/mother vacation" to Brazil. How fun! You tell him that you're all going to take in the sights and local culture - - for a change of atmosphere and to get his mind off things for a couple of weeks. That's the story you tell him.
Then, you take yourself and him to get your pictures taken for your Passports.
Then, after you get your Passports, you buy two tickets to Brazil - - a round trip ticket for you and hubby, and a one-way ticket for the kid (starting to get the picture?).
You all fly to Brazil.
You get into a cab from the airport and go to the hotel where you've previously made room arrangements.
You get to the hotel and get to your rooms, but do not unpack your bags!
After getting him settled into his room, you take his Passport without letting him see you. You then tell him you're going to the gift shop for a magazine.
However, the reality is that you're going to the front desk with an envelope. In the envelope is two hundred dollars in Brazilian money, and your note to him - -
"Dear Sweety Pie:
So, you think you're old enough to dislike me and Dad, and to give us continual trouble? Then you're old enough to take care of yourself. I hope you like your new home and country. New languages are fun to learn, aren't they? Here's $200.00 to get you started in life. Don't waste it. Love, Mom and Dad."
Have the hotel clerk deliver the envelope to his room.
Then, you turn on your heels, take your bags out of the hotel, hail a cab, and get back to the airport. Fly home.
Let Brazil take care of him.
