I remembered, by the way, that after I talked to him, when he went home, I was picking up coins on the ground. I was walking, and I saw a ruble under my feet. I picked it up, and then I noticed two more rubles nearby. I took those, and then my eye caught a few five-ruble and ten-ruble coins. I collected about fifty rubles, and then I ran out of money.
And then someone told me that this is a dangerous area and that I should leave.
