"You think too much."
"It's better to think too much than to not think at all."
"No, not really. Not thinking at all seems a better option. You don't think of troubles, you don't think of pain, you don't think of guilt, or regret-"
"-Yes but you don't think of love. You don't think of happiness either, and you don't think of a great many other wonderful and beautiful things. So what will become of you? Some brainless doll?"
"Emotionless. And content at that."
"Well then I think you're too easily content. I would rather feel the greatest hurt to know that at that cost I can feel the greatest love as well. No pain no gain."
