(Some adults still live by these rules!)

If I like it, it's mine!

If it's in my hand, it's mine!

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

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

If it's mine, it must never appear
    to be yours in any way.

If I'm doing or building something,
   all of the pieces are mine!

If I saw it first, it's mine!

If it looks like mine, it's mine!

If you are playing with something
   and put it down, it becomes mine!

If it's broken, it's yours!
