There were two women throwing a frisbee back and forth over a body of water. I was at the head of the body of water and indicated to the woman on my left that I would like to receive the frisbee. She tossed it too me and I tossed it to the woman on the right but I didn’t toss it very well and it wobbled a bit and went off course. She exclaimed that I needed to throw it with two fingers. I didn’t understand what she was talking about but surmised that she must be British. She toss it to the woman on my left again. That woman, instead of tossing directly too me, threw it into a breeze far above my head with the intention of it swooping back down toward me. There was a person walking under the path of the frisbee and as it arced and proceeded back toward me, and lost its draft and was falling toward the person walking toward me. I thought about warning him but didn’t think that chance was too high that it would collide with him. I was wrong. It proceeded to careen down rapidly nailing him right in the head. I felt guilty for not having warned him and walked up to him and apologized for not doing so.
