Me: “You should do this for money.”
He: “If I was good at it, I would.”
Me: “Hold my hand.  Give me whatever impressions come to mind.”
He: “The first thing is a man in a sailor suit, he came right away.” Next, “elephants with their trunks going wild.”
Me: “I rest my case.”  
Earlier in the day I did a reading, and the client sent me a photo of her father in a sailor suit.  I laundered all the wall hangings today and also included the footstool cover, which depicts dozens of elephants with upraised trunks.   I count that as two direct hits.  If you want to keep your skills up, all it takes is practice.
