looking at your picture I suspect you are elder by 3 years
Older--not, of course, necessarily wiser. I did grow up thinking that, notwithstanding the evidence of my own parents, grownups as a class somehow had it figured out, and that in the fullness of time I, too, would come into my inheritance, this knowledge, this self-assurance, this certainty that I knew how the world was wired. Probably before I was thirty it had dawned on me intellectually that the grownups were in fact making it up as they went along, and that each generation invented the wheel, but I believe I made it all the way to my early thirties before this awful conclusion finally resonated in my gut.
ruefully,
