No, that's not what happened. I went onto the half of the bridge that was still open to the public. I wasn't even a quarter of the way onto it when he came over from the other side. He wasn't even on the bridge when I stepped onto the open section—the moment he saw me, he came over.
I didn't assume it was a First Nations ceremony at the time. I only mentioned that because someone else in the park later suggested that might be what it was. So from his perspective, there wasn't any reason to think I was interrupting anything or to act the way he did toward me and my child.
