I visited my grandparents yesterday. I was told another splendid story! Some years ago my grandpa Vova had a mongrel called Bim. The dog was very amicable, affectionate and lovable. Vova gave that funny whelp to our family and he had been living with us in the center of Saint-Petersburg near the Finnish bay for some time. We got used to the pup, but Vova took him to his dacha so that he could live there in safety. We agreed. Time flew like an arrow and Bim got old. My grandfather sent him to his old friend Petrovich. Everything was all right. And in a few months we came to see our darling doggie. But there wasn't any barking when we arrived. Strange. Petrovich met us, gave some tea and showed a very well-known (for us ofc) fell... Then people said to my grandpa that Petrovich liked eating dogs, especially mongrels...
This is it! At times you know a person not badly, communicate with him, visit him... but his preferences haven't been discovered yet.
How to deal with people if you know that each of them is unpredictable?
