Good old Love.

Once there was an island on which all feelings resided: Happiness, Sadness, Hatred, Knowledge and all the others including Love. One day it was announced to the feelings that the island would sink and in order to save themselves they all constructed boats and set sail. All, except Love.
Love was the only one that stayed. Love wanted to hold out until the last possible moment. When the island had almost sunk Love decided to ask for help. Richness was passing by in a grand boat. Love said, "Richness, can you take me with you?"
Richness answered, "No, I can't. There is no place here for you." And Love got variations of that answer from everyone: Distress and Exhileration, Depression and Ecstacy. All of them. Love's shoulders slumped and head bowed.
Suddenly there came a voice, "Come, Love, I will take you." It was an elder. So blessed and overjoyed, Love forgot to even ask the elder where they were going. When they arrived on dry land, the elder went her own way. Realising how much was owed to the elder, Love asked Knowledge, another elder, "Who helped me?" "It was Time," Knowledge answered.
"Time?" asked Love. "But why did Time help me?"
Knowledge smiled with deep wisdom and answered, "Because only Time is capable of understanding how valuable Love IS."
