Today's words of wisdom come (yes, again; it's a neat book) from James and Claudia Altucher's The Power of No:

Rushing our words means fear. It shows our inability to pay attention, to be present. It reflects that we don't want to let anything in, we must fill in the silences, and we think we know better. (...) Acknowledge to yourself that real communication doesn't happen in the words; it happens in the silence between the words.

Right. I'll shut up then.
