I am watching an episode of “The Andy Griffith Show” and Deputy Barney Fife is having a dilemma over a chain letter. People are giving him grief over sending it so it won’t be bad luck. Chain letters still exist in a new form known as spam email. It’s a reminder that old school evolves into new school all the time. I for one have never responded to a spam letter or a chain letter for that matter. Superstitions can get the best of us when it comes to chain letters and spam. However we can be smart about it.
