In the 1970s, my grandmother went on a trip to Sochi. Their group was accompanied by a guide, let it be Vera, as the grandmother said, a very good woman. They became friends during the trip.
Once it turned out that Vera was from Omsk, like my grandmother. The further dialogue:
B: On which street do you live?
A: Oh, I live in the most beautiful place of Omsk, on the Irtysh Shore.
B is yes? I am there too. In which house?
A: In such a way.
B: I am the same. And the apartment?
A: The 55th
B is :? I have 56!
This is how my grandmother met her neighbors. Then they communicated for a few more years until Vera moved.
