amber_fire and I were playing complete the sentence, and this happened:
Me: "When someone makes you cry..."
amber_fire: "It means that they were important enough to you to make you cry."
Me: "It means that there's someone out there waiting to make you smile."
And now - (I'm not sure if that's exactly what she said but) - Were important enough to you. People who are important to you don't always stay important to you. Some do. Some don't.
Some will always be.
