"Disturbingly, "how are you?" is one of those phrases. "...yeah, but it gets worse..they don't even say THAT much...they say 'howyadoin?'...I sometimes listen to radio talk shows on NPR, and there are people who simple cannot begin a conversation unless they mouth that first!...even if the last 6 callers have asked the same question, and the host has said 'fine'....I'm waiting for the host to say, "I was JUST fine the last time someone asked, 2 minutes ago, and I am STILL fine...now ask yer damn question"
It's so bad there's even a commercial with this Texan in a bar telling everyone exactly how he's 'doin'..*grin*...
So, yes, one does begin to suspect that people are speaking in a lot of rote phrases, and not thinking about what they are doing...(and I put a lot of the 'hooray for America' signs since 9/11 in that category.)
Offers of Prayer may be, in fact, the closest to serious some folks get.
