@Mark_self and very nice people too! Those people who have been living in this city for a long time, since the Soviet era, are called by the cozy word "Leningradsy".
Sometimes you can recognize them by sight - they have kind faces. And if you're lost and don't know where to go in the city, you should ask them. A couple of times I was not just guided, but escorted to the place where I needed to go, with the words: "I'm not on my way, but come on, I'll walk you so you don't get lost!"
