Frustrations of older generations

Previous generations often act disappointed but most of them aren't. They act this way though, because they are frustrated and envious on the fact that many of us didn't make the same mistakes as early as they did,  and as they know the meaning of a lesson,  they wanted that for us too.  The timing is different though, as there is a time for each and everything to happen to each and everyone.  Plus... We have our own lessons to learn many of them different from what and how it used to be.
