I saw a man wearing a bike helmet, flailing his arms and following the little girls around. I kept jogging and saw a woman sitting on a park bench texting. She was completely out of site of the girls. I kindly asked her if she was their mother. When she replied 'yes', I told her that I saw a man talking to her daughters and that he looked like a weirdo...that's when she told me that the 'weirdo' was her disabled brother. I apologized to her and took off. I'm not a judgmental person; I was acting on my instincts as a woman to protect these young girls. Believe me, I'm mortified!!!
