Rome:

Cicero had his own beliefs on friendship. Cicero believed that in order to have a true friendship with someone one must have complete honesty, truth and trust. Also, friends do things for each other without expectation of repayment. If a friend is about to do something wrong, one should not compromise one's morals. One should explain what is wrong about the action, and help one's friend understand what is right, because Cicero believed that ignorance is the cause of evil. Finally, friendships come to an end because one person in the friendship becomes evil.

Russia:

The relationship is constructed differently in different cultures. In Russia, for example, one typically accords very few people the status of "friend". These friendships, however, make up in intensity what they lack in number. Friends are entitled to call each other by their first names alone, and to use diminutives. A norm of polite behaviour is addressing "acquaintances" by full first name plus patronymic. These could include relationships which elsewhere would be qualified as real friendships, such as workplace relationships of long standing, neighbors with whom one shares an occasional meal and visit, and so on. Physical contact between friends is expected, and friends, whether or not of the same sex, will embrace, sometimes kiss and walk in public with their arms around each other, or arm-in-arm, or hand-in-hand.

Asia:

In the Middle East and Central Asia, male friendships, while less restricted than in Russia, tend also to be reserved and respectable in nature. They may use nick names and diminutive forms of their first names.
