He's right.

From Jonathan Carroll's blog:

Almost everyone has some person from the past who continues to stick in
their soul like a deep splinter. You know who I'm talking about. The most
obvious example is the lover who dumped you years ago for reasons you still
don't understand, or accept. The bully who tormented you in school, the teacher
who inspired you and opened doors in your brain or soul that you didn't know
existed. A neighbor who suffered and died with dignity but remained kind and
thoughtful right up until the end. Ironically in some cases if you were to go to
these people now and tell them what a lasting effect they have had on you, they
would be genuinely surprised or perplexed. Because in truth you were only a very
small cloud on their horizon, a blip on their screen, or someone they forgot
very quickly. But boy, you sure remember *them*.
