Don't delete that video from the first Avenged Sevenfold show you saw. It's the only time you'll ever get a chance to see The Rev perform, and you have his drums--his, not Mike's--on live recording. Don't delete the video on accident. Just skip the pictures of Buckcherry. They weren't that great live, anyway.
Go to his deatbhed. Don't let him die without telling him how badly he hurt you; how much of a monster he is. But even more than that, don't let him die thinking you'll never forgive him.
Say goodbye to him. It's the last time you'll see him alive, and you're going to feel guilty for the rest of your life if you don't just let him know how much you love him.
Go to Travis's apartment with him that day after school like he wanted you to. It's one of the last times you're ever going to see him.
Tell Brian how important he was to you, and how much of an older brother you viewed him as even though he was never your older brother. Tell him how much you respect him and look up to him, and how you want to be half the person he is to turn out okay. He dies too young, and you don't have a lot of time to say this to him.
