You never know what conversation will turn up

On the phone with my friend Mark this morning.  He made a chance remark about something I had said a few weeks earlier ... He explained what that had made him think of ...

Then I picked up on a slip of the tongue he made and we tried assuming that his "mistake" was actually a message from his unconscious mind.  We played around with that for a bit and within a few minutes we had cracked a problem that had bugged him for ages.

He's confident that he will be able to enrich his work with a bit of his own magic.  Circle squared, thanks to an open-ended conversation between open-minded guys.
