From Garrison Keillor (ineligantantly paraphrased by me): Look people who casually cross your path (busdriver, doorman, person sitting next to you at the game, etc etc) and be comfortable in having some very brief casual conversation, just to really acknowlege them as people. The classic "hows the weather" kind of extremely casual chit chat. Garrison's point was with teens doing so very much interaction electronically, they are losing touch with actual interaction.
