What(dramatic pause) exactly is the purpose of telling someone to "take care", "drive safe", "be safe" or even "have fun" and so on? I mean is the person you're telling this to supposed to remember these verbal gems at the right moment and suddenly adjust their mannerisms because YOU told them to? I understand it's normal protocal, good manners, routine, habit, etc. but I'm becoming more leery of these often uttered phrases that in the end, mean nothing. It's as if in lew of saying simply "good-bye" or "bye" people have to get personal and cast this magical verbal spell upon someone that is leaving. Hey I'm driving like an ass but I just remembered that Gary told me to drive safe so I better do so! And what exactly does "take care" mean? Take care of what and how? Is "take care" and other likewise verbal good gestures pseudo-blessings in disguise? As if you're invoking a spirit or an angel that will suddenly attach itself to the person you tell this to because otherwise it won't happen and the person that's leaving will NOT take care or be safe and for that matter die a horrible death? OH GOD they're dead! If I'd only told them to "take care" or "drive safe" they wouldn't have died! Shit I told them to "have fun" instead! Might as well tell someone "May the Force be with you" or "Live long and prosper". Man I better live long and prosper because, you know, he told me to. So are any of these old sayings commands, orders, blessings, friendly gestures, useless words or something else?
