But this photo makes us feel happy - and we're not alone.
First posted on Reddit, the image depicts a subway passenger fast asleep on the shoulder of a stranger sitting next to him on the Q Line in Brooklyn.
After the compassionate gesture went viral this week, the nice man on the right was identified as Isaac Theil. And he told Tablet Magazine why he was content to be used as a human pillow.
"I simply remembered the times my own head would bop on someone’s shoulder because I was so tired after a long day," Theil said.
