finally i get reorientation of story. You can make us feel sad but also feel better to solve this story. We know sometime we make a mistake, and try to fix it. We know how John and Susan feel. what then happens is to regret the events that happened to them. if we are positioned as John or Susan it will be very difficult to behave. and allowing yourself to be a candle that is willing to burn for the good of all so that light at night will always be real and eliminate darkness. But it's hard for us to do it too.
there are only traces left on the faces of John's children whether Marry or Susan realize it will immediately remind John.
Complication with a tragic solution. Sad ending doesn't have to be unattractive ...
you are a creative writer.
warm regard from Indonesia.
