(Knock, knock…)
M: Come in.
W: Good morning, Mr. Brown.
M: Oh, come in, Mary. I’ve been expecting you. Take a seat.
W: Thanks.
M: And what can I do for you?
W: Well, I was thinking about taking a year off after we finish school this summer, and I wanted some advice.
M: I see. You mean putting off going to university for a year?
W: That’s right. I’ve been offered a place at London University, but what I’d really like to do is take a year out first — do something different, maybe go abroad.
M: So were you thinking of getting some sort of job, or traveling around? I mean, is your main aim to earn some money, or to do something else? Or do you want to do a bit of both?
W: I’d really like to travel — but I don’t have any money. But I’ve heard of an organization called Peterson International — and that’s what I want to ask you about. Do you know anything about it?
M: Sure. It’s a charity and it’s aimed very much at young people like you, and what they do is to get teams of young people to work together on various projects all over the world — environment projects, community projects, that sort of thing.
W: Mum, it sounds great. Is it just English people on the projects?
M: No, they’re international teams. You’d be working with quite a variety of people.
