Small acts of kindness are what makes the world go ’round, especially because we never know how far they can go.

According to tickld.com, one high school student had no idea how big of an impact he had on his friend’s life until they graduated.

The student, who didn’t identify himself, said he met his friend, Kyle, while heading home from school. Kyle was being bullied and carrying a huge pile of books.

The student helped him up and the pair began to talk. Shortly after, they became friends, then best friends. It wasn’t until they graduated that he learned what helping Kyle that day meant.

As he started his speech, he cleared his throat, and began. “Graduation is a time to thank those who helped you make it through those tough years. Your parents, you teachers, your siblings, maybe a coach—but most your friends. I am here to tell all of you that being a friend to someone is the best gift you can give them. I am going to tell you a story.” I just looked at my friend in disbelief as he told the story of the first day we met He had planned to kill himself over the weekend. He talked of how he had cleaned out his locker so his Mom wouldn’t have to do it later and was carrying his stuff home. He looked hard at me and gave me a little smile. “Thankfully, I was saved. My friend saved me from doing the unspeakable.”

Keep this in mind: Acts of kindness, no matter how small, have huge consequences.
