Sometimes, a small gesture can have a big impact - exactly the idea behind this video from three teenagers in New York.
After the Boston Marathon Bombings, the young men decided to stand on a busy street with a sign inviting people to meet a Muslim person.
In this one, they say they're hoping to "spread love and happiness and unity" and show people the true meaning of Islam.
Many people stop to shake their hands, have a quick chat or take photos. But as the video ends, things take an ugly turn - courtesy of one man.
The rest of the video however is great and inspiring, closing with the message "Just like race doesn't define who you are as a person, religion doesn't define your character."
"It is what's inside your heart that shows who you truly are."
