More time

While discussing time with Brooke and David over the weekend, I realize I have another time-quasi-picture in my head for the decades of the last hundred years or so.   When I think of the years of the past decade and the 20th Century, I vaguely see them in my head as a series of stepping-stone-like tiles, sloping downward and backward from the present. They are grouped in tens, by decade. The 60s have President Johnson hanging over them spectrally. The 40s are warmer-hued and darker.
