There's something about autumn leaves. They are so vivid, but we know they won't last long.
Next, consider the fence post. Is it not also transient? True, the fence lasts longer than the colored leaves on the climbing vine. But sure enough, one day that fence post fell over. I had to replace it. The post that stands there now is stronger; sturdier; but it lacks the character of this one.
People's lives are like that.
