This reminds me of an "accident" I had. I was walking down the sidewalk and noticed a gal on the third floor of a building, leaning on the window ledge with her hands, looking out. I looked up at her and she looked at me. I kept walking while looking at her and walked into a large planter which held a tree.
The planter was about three feet tall which abruptly stopped me. However, having been walking the force of motion caused the upper part of my body to lurch forward hitting my head on the trunk of the tree.
She laughed, I waved and carried on. Fortunately, there wasn't anyone else close by to witness the event. I never thought of suing her on the grounds of looking so good.
