Maybe I don't know, in general, my grandmother's neighbors from China appeared (students rent an apartment) so one day one comes and says, "Give me an egg, please, I'll give you two." Well, my grandmother gave me an egg and said that I don’t need to give, and then the Chinese woman said that they have a tradition of giving everything in a double amount and then my grandmother said: “And if you give 50 dollars, then you believe 100?” Chinese honestly spoke of this logic)))
