People that live in Philly treat the city, it's streets and buildings like they outwardly hate it and are fighting against making their own surroundings livable. No other place in the US where you will see people just throwing garbage on the ground almost as if it's a sport or city planners trying to fuck up the historical significance of buildings and neighborhoods. Folks only defend and support their city in words when an outsider is critical, spending more time and effort trying to come up with why Philly is better than X than it would take to, you know, pick up that WaWa cup you just tossed on the ground.
