Greta again., page-25

The flaw in that agrument is that the young today will be the old of tomorrow, wise for the experience.

When I was 5 my parents knew everything.
When I was 15 i began to doubt my parents.
When I was 25 my parents knew buggar all.
When I was 35 I began to doubt myself.
When I was 45 I began to ask my parents for their opinion.
When I was 65 my children and I began to reason with one another. (My grand children were a different proposition)
When I was 85 (and still learning) somehow or other my children and their children seem to agree on most things. I also respect what my parents told me. as good training.
Overall agreement is that Greta is a nut case.
