Like Victor said, I never met Gary, but it sounds like he was a selfless man.
Something many of us should strive to be better at.
I'll bet he wasn't even aware of the fact that he was indeed selfless.
That is the essence of selflessness.
A truly selfless person does not wake up in the morning and say, "I think that I will do something selfless today."
That statement would let all of the air out of true selflessness.
A selfless person just is.
