      The Browns are the Smiths' neighbors. Mr. Brown's name is John. But when his neighbors talk about

him, they all call him "Mr. Going-to-do". Do you know why? Mr. Brown always says he is going to do

something, but he never does it. Every Saturday Mr. Brown goes to the Smiths' back door and talks to Mr.

Smith. He always says he is going to do something."I'm going to clean my house today." he says, or "I'm

going to wash my car tomorrow." Or "These trees in front of my house are too big. I'm going to cut them

down next week."Mr. Smith usually says: "Are you, John?" He knows his neighbor is not going to do anything.

Then he says: "Well, excuse me, John. I'm going to do some work it the house." And he doesn't. Mr. and Mrs.

Smith often say to their only son Dick: "Are you going to do something? Then do it! Don't be another 'Mr.

Going-to-do'!"
