Anyone have any? Mistakes that you've done that are so bad, those you regret more than you can handle and will always regret whenever you think back on it. Mistakes that you know will be under your last dying breaths when you're an old, wrinkly man. Maybe we can list some of them out so other people won't fuck up in the same way we did...
I have two to share.
*My dad and I were never close when I got older, and we fought often. He always called me a failure and said I'd never amount to anything. When he was in his hospital bed dying, he asked my Mom and the others where I was. I was outside in the lobby. He called for me, and they came out and told me, but I didn't go because I hated him. He died a few days later, and I still wonder every day what he wanted to say.
*If you ever meet a girl that you think you can marry, a girl who relates to you on every single synapse, don't ever overlook that. She caught me about to do something with another girl in one of my most shameful hours, and while I've done everything I can to make it up to her, and she's tried her best to forgive me, she couldn't, and she broke up with me. I don't think I'll ever forget the way she cried that day.
