Hello everyone.
Those of you who are familiar with this trick might help me a bit. Pretty please

So, the trick is easy, I just don't see the proper reason for the spectator to name the position of the remembered card. There should be a reason ... There is none in the book, the instructions are simple: the spectator names the position of the card and you reveal it in a waw! way.
When the spectator names the position it feels like: "Name the position please." "Oh, it was the seventh card." "Jolly ho, let me just count seven cards from the top and here is your card!"
Any idea what should be used as a reason for spectator to name the position and not suspect a thing? Or at least not too much.
Thanks
