A homeless man

He had the bluest eyes.  For a brief moment, i saw him, but I had to look away.  He wasn’t old, but his body looked old.  He was shaking, and could barely walk, even with a cane.  I wanted to do something for him, but I didn’t know what.  My fear and my brain told me to stay away.  I went into the store and bought a couple of things.  When I came out, he was gone.  Where did he go?  Does he have someone that will take care of him?  His time on earth is short, I’m afraid.
Why didn’t I talk to him, ask him if he needed help.  Offered him some water.
All I could do was say a prayer for him.  I hope he’s ok.  O
