Nothing 4 Nothing

Another adventure of "I Love Lucy"... but this one is true. This noon I was making myself a sandwich on the kitchen counter when all of a sudden a bug looking like a huge black ant crawled swiftly by my bread...shocked I didn't know what to hit it with so I grabbed the slice of lunch meat that was on the bread and already half covered with mayo...and used it to swacked the ant. So now I was without a sandwich and couldn't find the crawly thing dead or alive anywhere. He may live to attack another day? There should be a lesson learned in this but I don't know what it is!!!
