Take a pen and paper. Entitle the paper as
High School Friends.
Try to remember all your friends and classmates from all the time that you were in high school. A friend might be your classmate or not, write down all of them. Preferably, write down first names and last names if could not then either first name or last name for each.
Keep your paper in a safe place as you would require it in the next posts.
