This was in full display in New York after the Saturday night explosion in the Chelsea neighborhood of Manhattan.
Here's how people are making a difference through simple gestures:
They handed out coffee to cops
New Yorkers came out in large numbers to praise and thank first responders for their work. One of those stopping by was a local Starbucks employee who identified himself as Jermaine.
"I want to give y'all some coffee and some pastries," he said, passing bag after bag over barricades on Sunday afternoon.
"Thanks a lot, man," a man in a fire department shirt replied.
The gesture was captured in a 33-second clip posted by KnightNews.com.
"I wish I could give a little more," Jermaine told the officers, but by the look on their faces, he'd done plenty.
They offered free rooms and dinner
The popular West Village hotel, the Standard High Line, opened up its rooms to residents living within the attack area. In a Facebook post, the hotel said residents would proof of address could also eat for free.
