To Mr. J

Thank you for being an awesome teacher and for being amazing! This school year was so fun and I enjoyed it because if you.

I wish more teachers was like you. I will never forget you.

I look at you like my dad. I never met my real dad but it okay because you treat me like I’m your son.

You make me so happy. Always feeding me when I am hungry and hug me when I am sad.

I will never forget you Mr. J. I love you and I will never forget about you!

Love Markus
