There is a world where you wouldn't have to wait around for your 110 % to be recognized as such. Some people are worth a second chance and some are not. The key here is being honest with yourself. Why do they want to try? What is their motive? Is it fear? Is it more? Is it the memories? What more will they bring? It's the last question. And once you answer that, and you match it against your own behavior, your own awareness and your own motivation, you can then make a decision that is right you.
