Josef Schock' wife, a just acquired Russian friend, Martha and Josef Schock. We noted the Russian guy sitting on the adjacent park bench reading his Russian newspaper. Josef's wife spoke Russian so she brought the guy into our conversations. Josef introduced the first Russian person Martha and I met, and we were the first Americans the Russian guy met! This was the first joke that remove any suspicions he may have had. But he was very cautiously friendly to us in the end!
