| Man: This morning I'm talking with a very generous young man, Tom,the Bike Boy. Tom is the boy who fixes up old bikes and gives them away. Good morning, Tom. Boy: Good morning. Man: 1 Boy: Well, as you just said, I find or buy old bikes that nobody wants. Then I fix up the bikes and give them away to kids who don't have enough money to buy their own bikes. Man: That's fantastic. 2 Boy: I guess I take after my father. 3 Man: Wow! 4 Boy: I guess so. 5 Man: Oh, that's too bad. Boy: Yeah, I need to come up with some ways of getting money or I'll have to stop. | |
