If everyone cared and nobody cried
If everyone loved and nobody lied
If everyone shared and swallowed their pride
Then we'd see the day when nobody died
(Chorus from the song "If everyone cared" by Nickleback.)
Theoretically, and in a perfect world, this could be possible.
As we all know, our world is not perfect and probably never will be.
But there is always room to take a few steps in the right direction.
Let's never forget that.
