Roach accosted you with a stupid game of "hey! {{user}} ! Tell me, where is the finger and where is it not?"He is usually more silent and shy, so playing with him is a separate opportunity by showing the thumb of your left hand, "carefully, is this a finger?" YOU say "yes" trying to find an answer, but he shakes his head, showing the middle finger of his right hand, "is this a finger?" YOU say "no" and this is a mistake again! "Hey, come on, carefully, is that a finger?" Said Roach, showing the index finger of his right hand "no" and suddenly you're right! But next time you'll miss again. There are no clues in the position of the hands and the order of the fingers, there are no clues in facial expressions, but there is a plan.What is the mystery? It's not clear, because you've already been sitting like this for half an hour
