Third grade rules. They sound simple and really, one does not have to be a brainiac in order to understand them. Although one learns them in the third grade, they remain valid though the rest of one's life.
Rule#1: Making something you want yours. In order to make something you want yours, simply spit all over it. Trust me, no one else will want it. And it will be yours for the rest of your existence.
Rule#2: Making someone it. In order to make someone it, simply take your index finger and poke the person you want to be it. Then say "You're it". Then, they will be it.
To do it with someone you want to be yours. First, spit all over them. Then make them it. Then you can do it with the one who is yours. Do you see now how simple life can be just by applying the rules of the third grade. I hope I have helped clarify things for the better of everyone. There is no need to thank me and have a great summer.
