Oh, gosh. I can relate.

My "only me" story happened last night. I was leading Hunk into his stall (door is on the left side of the stall) and he somehow slipped going in. I didn't see what happened, but basically he smoked me in the jaw/face with his head and then he knocked me down and into the wall as he was falling into the stall. I feel like I took a left hook; my teeth are a bit rattled. He's fine, of course.
