Three criteria I might suggest:
I saw people experience true loss this week. Something so profoundly shook their lives that I would have crumbled if in their shoes. Instead, I was merely a witness. I could feel their loss and offer support, help, and encouragement. I showed love and friendship in ways that were so simple and obvious that I hope it wasn't even noticed. It didn't matter what I did. Those feeling loss showed such grace, strength, and uncompromised love for each other and for their loss that I was left humbled and even more sure that my trivial woes in this world are not worth airing to anyone else. Even my pain-in-the-ass shrink.
