There is nothing you can do when it's all been done. The best you can do is think of how it could have turned out. You might long for it to have turned out better, and you might wish you could have said or done things differently. But in the end nothing can be done or undone. All the things you have said and the things you have done, be them good or bad, will be remembered by those you you tryed to impress. Because after it's all been done theres no changing it.
