How my sister sliced and diced and hung my painting upside down trying to turn it into modern art.

I gave this painting to my sister. Because if I sold it I would never see it again She sliced it up and hung it upside down. When I saw it years later I was confused as to what it even was. I asked who did it and she told me "I did it". What? Then I realized if I turned it 180 degrees it was Lynville Falls in NC. I love this waterrfall. From above it looks like the waterfall is comming out of the rock face. I never finished the watefall I just blocked it out in white. I was going to paint over the white with grays and blues to suggest the water but I never did. I underpainted with white because I wanted the white to be the whitest to pop out. Since, I used 18 x 12 inches paper back then. I was able to reconstruct the painting. See the black outline. I also found photos that I had taken of Lynfille Falls and put them into the picture. I never finished the Waterfall which I left blocked out in white. The painting was also very dangerous to make. I was above the waterfall, looking down upon it from a high angle from a trail lookout. Fortunately, the lookout had a nice stone wall I could sit on, layout my chalks, and do the paining. I was about 200 feet above the falls sitting on the stone wall. It was also well off the tourist trail so I was left alone to paint it. This was a very difficult drawing to do as the perspective was very complicated. This is because I am looking down at the waterfall from above. This type of drawing is called foreshortening and is diffcult to get it right. I gave the unfis painting to her because it was the most dangerous and diffioult painting I had yet done. If i finished it and sold it I would never have seen it again. So I sent it tko my sister. My sister really sliced and diced up my painitng. I lost about 60% of the painting. What she did, was a insult to me as a artist: By trying to turn a representational painting into modern art. Who does that?
