     Hello, everyone. Here is something important for everyone going to London next month. As you

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,

and, of course, it's very important that you take the school letter. While you're there, if you have any

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

and the person to ask for is Mr. s Belcher…She's in the office from nine o'clock in the morning until

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