about how everyone is so nice

When you move somewhere new, you might find a lot of the people there are nice. This is because you are more likely to ask people for help and information and, naturally, they oblige best they can. Where you're from, you rarely had to ask people for help because you knew the area, the weather patterns and expectations, the laws and ordinances, and so on. So people there were just people you had to share the city with. Your new neighbors are people you try to get along with.
