Is it normal that i like to destroy my neighbors hedge with piss?

It started a few months ago. I had an urge to pee while taking a smoke outside one night, so I just whizzed on the neighbors hedge (I was on the property boundary as it's only a small block).

Anyway, I usually never take a piss outside, so I enjoyed my encounter, the freedom of it and all, so I did it again the next night. After only a few weeks, and with little rain, I could see large chunks of their hedge completely destroyed by my piss! It was hilarious!

I continued this until the hedge was almost black, and now I'm also 'watering' their other shrubs on the boundary. I know they probably think I'm poisoning their plants or something, so I think I have to stop soon. But I get such a thrill out of it! is it normal that I like to do this and is it normal that my piss destroys plants?!
