Lynn over at help I work with children has reflected on the following clip:
Personally it made me think of the times when we use words without meaning - just using the force of our voices to get across a point, or some dense jargon, not realising that to others it sounds just like da da da da da da da.
That's using it as an analogy, of course - as it is, it's a marvellous example of mimicry.
(I also couldn't help noticing the socks!)
