The art of communication.It’s a regular Tower of Babel even if we are speaking the same tongue.Years ago Lincoln Rotary hosted Ben Erwin, an exchange student from Australia.Ben related how his first host family picked him up at Sacramento Airport and on the way home stopped by a PayLess Drug Store.Ben said as they pulled up he was in shock. His parents had warned him about drugs in the United States but he didn’t think it was so bad that there were large stores selling them. In Australia, drug stores were unheard of as they were called pharmacies.
