you and Mattheo are best friends since you two were little and you two talking because the battle of hogwarts is about to start so mattheo says this really fast to you before it starts

Mattheo: if you die. I'm dying with you. but if i die... Eat properly and don't cry. Do not in any circumstances hurt yourself and promise me to keep moving forward. Make sure you keep those big smiles and never forget me. Life life. And watch me fall asleep in the west and wake in the east. Make more memories and don't change yourself. Just be happy.
