Where I lived in Chicago, people used string to section off their front garden. Move ahead 30 years later and everybody has tall chainlink fences around their lawns, with warning signs that threaten they'll call police.
Maybe it’s because I’ve lived in “suburbia” all my life, but sometimes that’s a thing, but not all the time, at least not where I live now. It would be a lie to say “everybody” has that. Anyway, if he’s saying that is what Chicago is like now, how’d he know? I’m not sure, I thought he was still banned from leaving Guam, but I seem to vaguely remember someone in the comments on another post saying that’s not true anymore, I dunno….
