Letter to You

My old friend, Hello! It's been almost ten years since we last met face to face. The vast distance between us makes it difficult for us to communicate. Sorry for not writing to you more often. When I took Karl to explore the south, he was not even ten years old. I used to be so proud of how brave and decisive he is. But I don't let Karl roam around the wilderness anymore. I know him, he's not like me. My health is getting worse, and I don't think I've got long left... So, my friend, I must ask you to help me. Please, take care of Karl when I'm gone. I'm sending him to you with this letter. You are my closest friend, I know you'll help me.
