I will never understand nostalgia.

Yes, I was born in 1996, so not quite 80s, but even my nostalgia being applied to life wouldn't mean mimicking old days. It would mean making some comfortable change in what exists now. Like there's an abandoned cinema building (belonged to USSR ministry of defense, then was a small auto dealership, then was rented to shops and cat owner events, and finally it turned out nobody can untangle who really owns it, and if it's still Russian military of defense or private property) nearby, and the ownership issues with it have apparently been almost resolved.

So there are from time to time posts in our house chat about this or that plan involving something being built in place of that building.

That's not needed. If they demolish it, they can just make sort of an antique amphitheater with low benches to seat on. Just a place with many benches and trees around, formed so that people in it can all see each other. And it's weird, it seems someone doesn't like benches in Moscow, there are fewer and fewer of them on the streets and in parks and everywhere.

I mean, yeah, realty costs are a bitch there, but apparently nobody needs that particular place if the building has an owner, but is in fact used as a toilet for homeless people.
