Seasonal changes are great.
How about -— for long periods of time -— change in
the value of money? Inflation.
I guess what we are looking at are the things changed by time. ‘Time Changes Everything’ -— Bob Wills.
Let us say we are reading a book about Sequoyah -— his last journey toward Mexico.
Let us say they pause at a river crossing and one of his friends looks up at trash high in the trees, and says,
“I passed by here when the flood was that high, during the spring floods.”
Tells us the friend has been on this trail before, probably the year before, and hopefully knows the way into Texas and toward the Mexican border.
Wow, I am thinking of a whole lot of them.
Have a character look in the mirror and see time on her face would be good. A few more wrinkles and gray hair.
