You can't get back across if you burn the bridge

If you burn all your bridges as you get angry throughout your life it will only make you angry when you can't get back across to get to the other side to choose to go a different way. Don't act shocked when even those that you thought for some reason, no matter what you put them through, they would always be there for you are no longer there. Your anger and actions done out of anger can take it's toll and the ones that were there for you will have to burn their bridge so you can't hurt them anymore.
