There were many other ways I could have responded to the words and tone the individual used but in the space and time of the event silence felt like the best option.
I've learned that I don't have to react to what another says. It often has little to do with me, anyway.
Will I always remain silent in the presence of verbal barbs? Probably not. I'm Human and will, at times, feel the need to defend myself. But from now on I will at least give myself the option of practicing the wisdom of staying silent.
