Recently, my son told me he was worried about my stress levels after seeing a photo of me appearing to be screaming at someone. As it turns out, I was leading a chant at a rally and I had to shout at the top of my lungs to be heard by the hundreds of people there. But it left me wondering how many pictures of an angry-looking me are out there. Anger and vitriol aren't the best way to get a point across.
