know, you are going to stay with a family for two weeks. Now, the most important thing is money.

You should take about $530 with you. I think it will be enough for everyone. Then, when you arrive,

your new family will meet you. You must remember to wear a red shirt, so the family will find you

problems, you can call Leech School Office. I'll give you the office phone number now: it's 580-4436

five in the afternoon every day. OK. That's everything. Have a good journey!
