Ctrl+Z

If I could use ctrl + Z in real life to undo anything I had said or done I don't know what u would use it for I don't regret the things I have done . Its actually most likely the other way around. I Would save this chance to erase a mistake for later on when their is a mistake I want to fix. But for now I don't need this "chance". I'm Okay with my life I don't regret things. So Yeah I would save this.
