1    If I like if, it's mine
2    If it is in my mouth, 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's mine, it must never appear to be yours
6    If I'm chewing something up, all of the pieces are mine
7    If it just looks like mine, it is mine
8    If I saw it first, it's mine
9    If you are playing with something and you put it down it automatically becomes mine
10  If is it broken, it's yours
