I was once run over by an 80 year old drink driver, and they lied about what my horse did.
The fact that they lied and then my story was not believed actually hurt more than the injuries to both me and my horse. In fact, I ended up wishing my horse HAD reared up, taken 6 steps backwards and launched himself over the bonnet of the car and through the windscreen. At least if that had of happened I could have moved on, but fighting lies was so hard for me.
I have a camera so I don't have to go through that particular pain again.
I may still have the accident, but I am likely to be believed as to what happened, as I will have proof.
