When I was a child, I used to gallop down the stairs like you'd see a lot of people doing in everyday life. I got to a point in my puberty that I had grown just enough to slam my head into the wooden stud at the bottom of my stairs going into the basement.
I'm pretty sure my IQ went down by about 25% that day.
I am born, raised, and live in one of the most diverse cities on the planet. I could care less about you assimilating to my culture. And I definitely don't care if you can't speak the language.
I got to disagree with the "learn the language and customs" thing. I live (also born and raised) in one of the most culturally diverse cities in America: Germantown, Maryland. I couldn't be prouder, and I also couldn't care less if you don't speak English.
His mind is made up. He's always been about money.
