All the hurt that is in the past should be left there, why fester upon what happened before? It is of no good use to anyone too rake through the past, yes, we have all made mistakes all we have to do is learn from them. In the days gone by and we have all had friends that have let us down, either let them go or forgive them. The past is where we learn to grow and to become wiser and greater, it is not a prison only if we choose it to be. Look to the past as an opportunity to gather knowledge and to use this wisdom to take a great and wiser step forward.
