Honesty [insert name], I really miss you and want you to come to my school, I have cool friends you would love. I miss hanging out in our free time and during lunch. I miss messing around in the stalls and all of our friends. We can start a new friend group and we can hang out more often, maybe even go to the park or movie after school. School is so boring without you. Your one of the only reasons I used to go.
-Sincerely [you]
Btw you can also transfer to their school!
