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 waved to strangers like that, and he said," I heard about some people who had tried but failed to commit suicide. Many of them said that if a stanger 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"
