Hillside, NJ is a middle and upper middle class town of mostly Portuguese and Africans bisected by
Route 22 and a set of train tracks. There is a small Jewish presence as well as a growing Hispanic presence. Upperclass residents either live in the more ostentatious Westminster section or invest a lot into designing the interior of their homes in the rest of Hillside as to not draw attention. Teens hang out at at Central Avenue Park ,
Short Hills Mall, Jersey Gardens Mall, or inside homes playing video games. Both parents work so there's very little
fraternizing with neighbors beyond small talk.

You're from Hillside, NJ? I figured as much since you do
well in school and speak really well but still manage to
play basketball and hang out wit. Your parents must have their
shit together. Property taxes are high.
