Too many people have an argument with their siblings, their parents, their friends and they burn the bridge out of anger.
Then the years pass, they get busy, the other person gets old and they realise during a moment of mental clarity that they actually wish they could argue with that person one more time and let them win this time.
But it's too late and that person isn't coming back. Life moves forward. Love and cherish your loved ones because you might not get them back. Nothing can bring you back together and nothing really has to bring you back together.
You have to be careful about how you live your life and how you take your risk because no one might be able to come and save you. You just have to keep moving forward, doing what you know how to do best and acting on it.
