Men love because they are afraid of themselves, afraid of the loneliness that lives in them, and need someone in whom they can lose themselves as smoke loses itself in the sky.
Once in a while, "great love" comes to your life. It probably won't last but it's good to know that at least once in your life, you had that kind of love.
The essential sadness is to go through life without loving. But it would be almost equally sad to leave this world without ever telling those you love.
