To start with friendship is a special relationship between two or more people of approximately the same age. 

On the one hand, friends usually spend a lot of time together. They often study at the same school or work at the same office. As a rule they trust each other their innermost thoughts, they tell each other their secrets. Sometimes real friends need some advice with various themes and issues. Friends often go out together, relax, and have fun. A true friend will never betray or hurt.     On the other hand there is so much wickedness in our world. And even friends may betray you. It is very painful and insulting. In some situations a man need to be bold, to be able to make a decision very quickly and not to lose esteem. And it is not easy. But there are much more good people around us. 

In conclusion, I would like to say that people can not live without friends, because a person is in need of kindness, love and devotion.

Начну с того, что дружба - это особые отношения двух людей примерно одного возраста. 

С одной стороны, друзья проводят вместе очень много времени. Они часто вместе учатся или работают. Как правило они доверяют друг другу самые сокровенные мысли и тайны, они рассказывают друг другу свои секреты, советуются по различным темам и вопросам. Чаще всего друзья вместе гуляют, отдыхают и веселятся. Настоящий друг никогда не предаст и не обидит.

С другой стороны, в мире так много подлости. И друзья нередко предают. Это очень больно и обидно. В некоторых ситуациях нужно проявить смелость, уметь быстро принять решение и не потерять чувство собственного достоинства. А это нелегко и не многие на такое. Но хороших людей вокруг нас больше. 

В заключение хочу сказать, что люди не могут жить без друзей, потому что человек нуждается в доброте, любви и преданности.
