Perhaps when you're older like me, at 63 you'll understand, or perhaps as a crusty incorrigable 64+ year old you've forgotten the follies of youth?

To say more would be ad hom. So I shall stop with a wise aphorism of my grandmother, born at the end of the 19th century:

if you have nothing nice to add, consider saying nothing.

I am sure that aphorism is quite apt for thesis defenses, critical debates, shareholder meetings, peer review, and forums of discussion.
