Cross cultural communication

I was walking across the street in Nuuk Greenland with a friend from Brooklyn NY. He was trying to talk to this very drunk guy who reverted to sign language, using one of the two hand signals that cross every cultural divide. The other is the OK sign, but what fun would that have been? We all cracked up including our new friend. It seems that Brooklyn boys and tough as nails Greenlanders have a similar sense of humor.
