Souls wait up in heaven for thousands of years, longing for their moment upon this earth to do another soul a favor.
Angels burn with jealousy each time a human being turns himself around and creates beauty in this world.
Heaven is nice, but on the best things, earth has exclusive rights.
You know what angels don't have: The natural gift to feel together with someone, very close and in a tenderly way, to experience love within the universe. For that they are mostly jealous for.
