Today I went to a Zoo by me with my in-laws and my 3 girls, twins 3 years old and my 15 month old baby. I can't really go anywhere unless someone goes with me and the girls, so the girls and I were really excited and happy about getting to the Zoo. When we were there, my father in law had to leave us briefly, but it seemed ok. I noticed a man standing across the path from my 3 year old daughter, who was playing in the sand pit. Because of the way she was positioned, a small portion of her "butt crack" was visible. When I saw this, my initial reaction was, maybe I should put sunscreen on it. I was pondering this when I heard the distinct sound of a cell phone picture click. As my head swung around to the sound, there was the same man, with his feet spread wide so he was closer to the ground, cell phone camera pointed at my daughter's rear. My first feeling was confusion and disbelief. And then the feeling of helplessness, disgust and wanting to flee. I scooped her up and immediately brought her to where her 15 month old sister sat in her stroller. The f***ing pervert was so excited, looking at his new picture, that he didn't notice that I was on to him. By the time my in-laws were helping me with my 3 girls and we had notified security, the freak had left the zoo. I am trying so hard not to beat myself up for the way I reacted and not to imagine what is happening to my daughter's picture, but I am having a really tough time with it. I feel like my PTSD was a part of my freezing and not just running over to the sick f*** and grabbing his phone. I am so upset that this happend because I am trying so hard not to be paranoid of everyone and I was doing ok in the crowded space and everything and now this. I am having such violent fantasies and I don't want to go to sleep.
