I don't hate teenagers.  They're...  you know...  teenagers.\n\nYou actually grow *out* of hating them the older you get.\n\nI have a theory on the ages of emotion.\n\n- Infant = fear\n- Child = wonder\n- Teenager = rage\n- Young adult = restlessness/impatience (*) \n- Adult = contentment\n- Senior = boredom\n- Geriatric = fear\n\n\nEDIT (*) Changed from "hate" as suggested by *speigelman*
