Cville Snow Street Parking Etiquette?

I’m new to the whole street parking at home lifestyle in a cville neighborhood. When it snowed, I shoveled all around my car and made the ability for my little car to get in and out. Due to the weather, much of the street parking is still frozen and unparkable unless you own a lifted 4x4 jeep. So today, someone has stolen my perfectly shoveled spot with their car (which infuriated me the likes of which I didn’t realize one could feel over a parking spot). But now I had to steal someone’s shoveled spot, which has sickened me to the core of my stomach. So in reflecting in anger and hypocrisy, I am left wondering…Are they an asshole for stealing my hard worked snow free parking spot? Am I now an asshole for stealing my neighbor’s? Might the one that stole from me be a parking spot victim themselves? Is there a patient zero asshole among us?!? What’s the etiquette, who’s the asshole(s), and should I be building a a snow wall around their car right now in an act of petty revenge!?!
