Last Friday, I was coming home late after spending time with friends and thought I’d go down to the $99 cent pizza place. On the way, I saw a man sitting on the stairs alone there. I’d seen him before every day I run late to work, but this time I had no place to rush off to.

There was something about him, a quiet manner, different from many of other homeless people I had seen in New York City. I walked past him, went to the pizza place, and those 10 seconds waiting in line was enough to practice stepping outside of my usual, familiar flow. So with a few slices in hand, I went back to join him. I asked him if he was hungry. He said yes, but not for pizza because it made him uncomfortable. He’d rather have a few bucks for chicken and rice since it was easier on his stomach. It’s funny, in that moment, he became more real to me.

This man I had seen almost every day was someone with specific conditions, needs, and experiences. We exchanged names and ended up talking for a little over an hour that night as Kevin told me stories from his life, how he had done things when “he was younger and didn’t know any better” and how he tried to make amends (补偿) but too much time had passed. He shared his views on the value for young adults to learn the history of other people.

He talked about his one wish being in his 60’s before he leaves this earth, which is to share his story with the teenagers and young adults so they could avoid the mistakes he went through. Throughout the conversation, he eventually got his chicken and rice and gifted me a rose he had been carrying. Shortly afterwards, I made my way home, thinking to myself, “I met an amazing homeless person”.
