Your Name
Your name is one of those things that identify you as you. But I'm not going to state obvious things about your name that may change the rest of your life, like having the name "McDonalds" or something like that. What I meant is the 'secret' behind it. Your name can easily determine the people you will make friends with in elementary school, intermediate school, high school, and possibly college.
The way it works is directly linked to the educational system in America. Almost 90% of all teachers use the alphabetic order of their new student's names to determine seating and other education related things. What this means is that Joan A. will most likely sit next to John B. because of the first letter of their name. It's as simple as that.
