What does it mean to be a good friend? It means always to be ready to help your friend and don't hope to get a compensation for it, and to alleviate sorrow of your friend.Two friends -it's "one soul in two bodies", as ancient Greeks said.Classical were examples of friendship from old tales:Castor and Pollux,Alexander the Great and Gefestion and others.
And friendship helped people to survive in extremal situations, particularly at war. When Russian tsar Peter I made acquaintance with some Dutchmen, Germans and other foreigners, it was the beginning of a long friendship. Among the of the best his friends were Franz Timmerman, and Franz Lefort. Both were friends of the Russian monarch, helped him very much in his labour of reforming Russia and were true his friends until death.300 years passed, but moral values have to be the same. We have to be as true friends as they were to the Russian emperor, because true fidelity is unchangeable and it cannot be valued by any money.
