The guard turns to the other one, and repeats the hand gesture with the middle finger.
"What do you think that means? ", he asked.
The other guard looks at the hand gesture, turning his head a bit. He answered.
"I am thinking it's one of those religious signs? Maybe Sharessian. It does kinda resemble a personal part."
With a grimace, the first guard responded,"Oh man! You are twisted. Obviously, it's a blessing of some sort, the man did say 'thank you' when he made this hand sign. "
The second man makes the same middle finger hand sign and with a smile says , "well Bless you too!".
