Haters destroyed my artwork

What would you feel if someone destroys your precious artwork? Would you be mad to that person who destroyed it? Last semester, when i went to my third class which was graphics, I noticed something that was missing, my artwork. I walked around the room to find Voltes V (my artwork) and later on i found it inside a room. I know you would say "it is just an artwork, it could obviously fit in a room" but let me tell you, it is not just an artwork, and it cannot fit in a room. Me and my partner Christian made Voltes V for a month. We spent our spare time and lunch time making it. I made it's head,body, arms, shoulders, and it's accessories. Before we started making the project, I made a blueprint for our guide but after a few days, the blueprint disappeared. I got a little mad because i spent almost an hour doing it. But let's get back to the track, Voltes V was made out of recycled boxes, cardboards, and papers so it could get easily broken meaning, it has to be taken care of. At the end of semester one, Mr. Hill, my graphics teacher, told me that i should take Voltes V home beacause the room needed more space. but there was one big problem, my partner and i cannot take it home because it is too big for both of our houses. Then one day, when we were about to check our project, we found it in a room, with missing parts, broken legs, and a broken shoulder. Now, imagine you were the one who built the artwork for one month. Imagine that you worked hard for it, for a perfect mark and then later on, someone destroys it.Luckily, today, the project is now safe in my T.A.'s classroom.In my opinion and definitely everyone's, people should not destroy other people's work because it is not theirs.
