My wife is conversational putty...

What the? Yes, conversational putty – you read correctly! It is self-confessed. My wife is a very chatty out-going and funny person, and during a discussion the other day she informed us of this title for someone who is good at filling in the awkward silences, "gaps", within a conversation – hence, conversational putty :-)

I have discovered a further reference to this title, in slightly different context, here.
