You have a very nice house with a garden, and in this garden you grow a lot of things, but the best thing of all is your apple tree. You are very proud of the apples that you get from your tree; they are big and juicy, a treat to eat.
Lately, however, you have noticed that the apples keep disappearing. One evening, after dark, you hear sounds out in the garden, and go out to see what it is. You are just able to recognise three small boys stealing your apples! You shout and the boys run off, but you know that they will be back again once they think you are not looking.
You know who the boys are. They are three brothers who live a few streets away.
