Our gate was ruined

A few days before Christmas, a neighbor was learning how to ride a motorcycle. I saw her stopping right in front of our gate and I felt like she has a problem. As I went out of the door, I heard a loud noise. That’s when I realized that I was too late. The motorcycle had hit our gate and ruined it. The girl had a bump on her head.

I wonder how the motorcycle could destroy the gate when it was just 3 feet away. No one could explain but I saw it as it happened because I was already out of our glass door and had seen the head of the girl moving toward the gate prior to the loud sound. This is one mystery that I wanted to solve because I suspect that a mysterious force had done it again on our gate.
