The hardest thing to sever in the world is affection, the hardest thing to seek is love, the hardest thing to repay is a favor, the hardest thing to obtain is friendship, the hardest thing to divide is family love, the hardest thing to find is true feelings, the most painful thing is heartlessness, the hardest thing to guess is mood, the hardest thing to repay is gratitude, the most painful is self-infatuation, and the most lovable is your smiling expression!
