Hey Senpai,
Hey Haylee, I wish you were here... I’ve had to deal with a lot of things without you... school has gotten worse since you moved away, the bullies have been targeting me. They throw rocks at me, they say I should never have been born... but I am getting used to it. I can’t wait till I get to go to your house, is it cool? Is the neighborhood cool? I have a ton of questions, but we both know if it sucked, you’d move back here lol well, I love you... hope you feel great and are being appreciated
Yours truly, The polite Senpai
