Also I personally find the statement that "life will teach the lessons" a bit odd if it's used to make the LBS to feel good. It is only there to prevent the LBS to falling into doing stupid things. It feels sometimes that we believe too much that the WAS won't be happy, karma will do something or that they will learn and realize their mistakes later on. Way more often than not they don't. However I do agree it's not the LBSs job to show it or teach the WAS.
