“The young people of today think of nothing but themselves. They have no reverence for parents or old age. They are impatient of all restraint. They talk as if they alone knew everything and what passes for wisdom with us is foolishness with them. As for girls, they are forward, immodest and unwomanly in speech, behaviour and dress.”
I believe that Socrates or Plato said this. As you get older, and sometimes more responsible, the irresponsibility of your past seems to fade somewhat.
