To mourn the passing of a man you didn't know is the very essence of the human condition.

• Whether he made you laugh--and he did on occasion.
• Or educated you--which he did on occasion also.
• Or even if he annoyed you occasionally--which he also did.

He stimulated you; caused you to think; emote; react; what more can you ask of stranger.

There is a poem that I first became aware of through a movie that I --possibly controversially--rate as one of the best ever made:

I never knew a wild thing
That felt sorry for itself.
A small bird will fall frozen dead from a bough
Without ever having felt sorry for itself.
- D. H. Lawrence

To feel sorry for oneself is arguably a characteristic unique to the human species.

As is, feeling sorry for another(*).

Could you have one without the other?

Is not sympathy the very essence of humanity?

Farewell Blazar. The world is a poorer place for your passing.

(*)There is some evidence to support the supposition that elephants are capable of feeling sorrow for the loss of another of their aquaintance.
