Here is a joke I like:

Q. What’s the difference between amnesia, ambivalence, and apathy?

A. I can’t remember, either way it doesn’t matter, and I don’t care.

I’ve heard that what a person finds funny is indicative of unresolved problems in the subconscious. Maybe I laugh at this joke because it represents an ability to let go, something I don’t possess: I do remember, I know that it does matter, and I do care. But despite all my worrying and wondering, I haven’t figured out why, twice in nine months, I was the object — the victim, even — of random violence. What lesson am I supposed to learn?
