Well the time had now come for him to tell his friend what he wanted to say ever since he ran away. Since he didn't want to say it he simply wrote a letter. It went like this:
Dear Best Friend, This is really weird cause I've never done this. Once you read this please don't blame yourself. I think that us being together isn't the best thing but not the worst. I'm not saying I don't wanna be friends, I just can't trust you the same. It's in no way you, its me. I just think that you will be better off without me, like not worrying about your best friend who's not eating as much! So we can still be friends no lie, but it will be different. Your always in my heart no matter what we don't say to eachother.
Well this is the time that you start crying or even sobing, but no. His friend never saw the letter. He rather put it in a letter that his friend got him. Even though now they are best friends and there will always be a secret between them.
