John: Have you planned your summer holiday yet?
Sam: Of course I'm leaving next Monday.
John: Where are you going?
Sam: My parents have booked me a week at Campbell's Adventure Camp.
John: Adventure Camp? What's that all about?
Sam: It's a teen camp in Redwood National Park.
John: Wow! You're lucky! I've never been to an adventure camp.
Sam: Well, do you fancy coming with me? If you come, you'll learn how to put up tents, build fires, make tree houses and survive in the forest!
John: Thanks but I'm afraid I can't.
Sam: Why not? Have you already made other plans?
John: No, I haven't.
I just don't think my parents will let me.
Sam: Well, if I talk to them, maybe they'll let you.
John: Really? Thanks, Sam! You're a true friend.
Sam: You know what they say. A friend in need is a friend indeed.
