Sometimes the smallest things can make the biggest differences. When Casey Fischer, a student at Southern New Hampshire University, began talking to a homeless man, she thought she was doing a good deed.

But when he pushed a hastily scrawled thank you note into her hands, she realized that for the price of a coffee and a bagel she might have just saved this man’s life.

Casey Fischer saw a homeless man singing on the road, begging for money.

On May 21st, 2015, Fischer, who has a young daughter, decided to use her long break between classes to head to the local Dunkin Donuts to buy some coffee.

Outside was a homeless person. He was singing on the side of the road, whilst also counting some change he had been collecting. He had just about $1, and after a time he stepped into the shop intent on buying himself some coffee.

Most people would probably ignore the man, but not Fischer. Instead, she was curious about his story and initiated a chat with him.

“I began to get super annoying and talk to him over and over again even when he didn’t really want to talk,” Fischer wrote in a Facebook post.

Since he only had $1, Fischer decided to buy the man a cup of coffee and a bagel and to sit and talk with some more.

They then spoke about his life for the next two hours.

The man, named Chris, was shocked at her generosity and remarked just how unique she was.

“He told me a lot about how people are usually very mean to him because he’s homeless,” Fischer wrote in a Facebook post.

But he also told her other things: about how drugs turned him into a “person he hated,” how his mother died of cancer, about how he never knew his father, and that Chris only hoped he could turn into someone who his mother would be proud of.

Fischer was touched by Chris—not just his story, but his manner, as well.

“Chris was one of the most honest & sincere people I’ve ever met,” Fischer wrote in a Facebook post.

In all, they ended up talking for around two hours, but eventually Fischer needed to return to class.

The man wanted to thank her, so he scrawled a hastily written note. When Casey read it, she was floored.

Before Casey left, Chris asked her to wait a moment. He wanted to write her a thank you note. They did not have any paper, so he scrawled a few words on the back of a crumpled-up receipt.

He then handed her the note, thanked her, and left.

But when Fischer read the note, she was stunned.

“I wanted to kill myself today, because of you I now do not,” The note read. “Thank you, beautiful person.”

For the price of a bagel, a coffee, and two hours of her time Fischer made a huge impact in this man’s life. It is something we can all do, if we take the time to try.

“When life seems to be failing us there are moments like this that take your breath away! Amazing,” wrote Dawn Papineau in the comment section of the Facebook post.
