As I read the metaphor that comes to mind is the Phoenix... Of that sad experience this nice piece of literature arose. (and also the realisation that this life's too short and anything could happen at anytime and so therefore we should treat those around us better, like its the last day they'd be around. This way we could avoid regrets and self blame no matter what happens. I read somewhere that all the flowers that would be placed on someone's grave would be more useful if we give them to the person when they are yet alive. I guess my point is that; she only realised she could have treated her mom better only when she caught a glimpse of losing her. We could be wiser and learn from stories like this. Do good to all... When it actually still counts)
