I pooped in a public hotel pool
No way. Why would you do something so disgusting?
I was fed up with my parents on the trip for being so controlling
I can't see how you thought that was an appropriate response to what your parents were doing?  Doing something that others find disgusting is wrong.
I couldn't give two shits, literally
I'm sorry your parents are very protective, but that doesn't give you the right to destroy property. How would other guests feel if they just wanted to enjoy themselves and saw they were in a bio hazard?
