As a child I saw how much energy grownups put into kissing and love type stuff. It seemed like a real waste of time, yet I knew one day I would want to spend time and energy the same way, 'cause it happened to everyone. I dreaded that.
Related to this, I saw how much people change mentally as they got older, and since the person I was at that moment would morph into someone completely different, who I was would essentially die to be replaced by this different creature. I still feel this way.
