For toddlers (and wives).

1. If I like it, it's mine.

2. If it is in my hands, it's mine.

3. If I can take it from you, it's mine.

4. If I had it a little while ago, it's mine.

5. If it looks like mine, it's mine.

6. If I am doing or building something, all the pieces are mine.

7. If I saw it first, it's mine.

8. If it is mine, it must never appear to be yours in any way.

9. If it is broken it's yours.
