“I noticed that my boyfriend would always wave to everyone while we were driving around. No matter who it was, he'd flash a smile, and wave happily even if they gave him weird looks and didn't wave back. I asked him why he wanted to strangers like that, and he said, "I heard about some people who have tried but failed to commit suicide. Many of them said that if a stranger had just acknowledged them with a smile or a wave, they wouldn't have tried to end their lives. I want to save a life today."
