If I like it; it's mine.
If it's in my mouth; 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 I'm chewing something up; all the pieces are mine.
If it's mine; it must never appear to be yours anyway.
If it just looks like mine; it's mine.
If I saw it first; it's mine.
If you are playing with something and you put it down: it automatically becomes mine.
If it's broken; it's yours.
