So ... why does everyone start a sentence with "So". Both verbally and in written media. This has bugged me for quite a while.
I've also been indoctrinated into it's use. It definitely assists conversation but ...
"Exactly" is another one (in London anyway). Recently "exactly" has come to mean absolutely anything. E.g. "I don't know what you're talking about but I'll say 'exactly' and nod my head as a lead in to what I want to say' or just to be sounding like I'm still in the conversation"
Weird how words like these become viral.
Mild rant over.
