In a slighly different vain: years ago I met an "elderly" (younger than i am now) English professor through a friend. I delighful man but by his own admission VERY shy. I noticed he worn TWO watches (we are talking 1970's here - all watches were just watches!), one on each wrist.
I asked him why he worn 2 watches. He said that becuase he was so shy he had great difficulty starting up a conversation with a stranger. The problem was STARTING the conversation. Once started he was fine.
He said that by wearing 2 watches people would, from time to time, as him WHY he worn 2 watches. BOOM, the conversation had been started! He explained why and after that everything was fine. The ice had been broken as they say!
I too wear 2 watches (sometimes), my "dress watch"I wear when I'm going out, and a Garmin fitness watch that keeps track of my activities. My "dress" watch is a very special watch (the Omega Moon watch - i have had it since the days of the moon landings) and occasionally someone will notice a a conversation is started!
