It really annoys me when people start all their sentences with "So...". In English you BARELY EVER start a sentence with "So..." and it's even rarer to use it to answer a direct question. I mean WTF? I thought this was a quick fad but it's been going on long enough and we have to put a stop to it. I'm starting a committee or something. It drives me fucking nuts. Learn to English.
SO SOrry, SOme of us SOmetimes SO bad at grammar 
Me too, every morning driving to work, every person being interviewed on the radio starts with "SO", AAARRRGGH, this is not the way to start a sentence, where did this come from, its nearly as annoying as the upward inflection which makes every statement sound like a question!
Ahahahha- you listen to npr constantly, don't you? I've noticed the same thing- every smart guy they interview answers questions the same way. I have no idea where this started btw. Just funny; you're not the only one who's noticed. non-passive-sentence-speakers; unite!
