It is always sad when someone leaves home, unless they are simply going around the corner and will return in a few minutes with ice-cream sandwiches.
The burning of a book is a sad, sad sight, for even though a book is nothing but ink and paper, it feels as if the ideas contained in the book are disappearing as the pages turn to ashes and the cover and binding--which is the term for the stitching and glue that holds the pages together--blacken and curl as the flames do their wicked work. When someone is burning a book, they are showing utter contempt for all of the thinking that produced its ideas, all of the labor that went into its words and sentences, and all of the trouble that befell the author . . .
The sad truth is the truth is sad.
Grief, a type of sadness that most often occurs when you have lost someone you love, is a sneaky thing, because it can disappear for a long time, and then pop back up when you least expect it.
The way sadness works is one of the strangest riddles of the world.
