My husband and I took off to Bafflo to help Mum move out of her apartment in Bafflo, New York. The plan was to pack everything into her van so that she could drive around visiting families and friends for the next ten days before heading back to her home in Florida.After dinner we headed back onto the road, Mum in the van with us behind in our rental car. The next moment changed everything: a deer jumped out in front of the van and Mum ran right into it. There was nothing she could do. It was awful. Police arrived. Calls were placed. The tow truck arrived. We moved essentials into our car and made plans to get Morn to a hotel near the garage. Everything fell into place in a mechanical way. And I worried about Mum, of course, but what troubled me most was the deer because it wasn"t dead. When the police officer shone his light around the accident scene, two beautiful brown eyes were frozen in the beam of light. It was lying down on someone"s front lawn, still, shocked, but very alive.I couldn"t even look at it. I asked the police officer if he could shoot it, but because it was a residential area, other methods were needed. The officers felt its legs to confirm that they were not broken, and gently pushed it, hoping that the push would inspire the poor animal to turn. But it sat there, probably suffering from internal injuries. And that caused me to feel a deep and powerful sadness. If that was a person lying in the ditch, there would be ambulances and doctors busily working to relieve pain and save life. But no, it was an animal, and there is no justice for animals.
