Does anyone happen to know, where does the phenomenon of starting any kind of story with the word 'so' come from? "So I was walking down the road and I bumped into my friend..." Has anyone else noticed this? Is it more prevalent in the US? (I'm from the UK, but I've been living in Washington D.C. for the past few months.) Does anyone know where it comes from? It must've come from somewhere. Is it actually that new, or am I just noticing it more? And where does it stand, stylistically-speaking?
