Friendship is a very important part of people's lives.  

If you want to be a good friend, you should understand and respect other people, be sociable and kind. And because of this, it is rather difficult to have a lot of friends.

You can have fun and interesting time with your friends. You can study, play, go for a walk and just talk with them; spend free (and not only free) time differently.

I have got five best friends. They are Masha, Sasha, Dasha, Vanya and Julia.

But people can't live without friends, because in this situation life become very boring and lonely.

True friends will always help you in a problem situation, and you can rely on them!

Trust, respect and kindness are the most important thigs for true friends.

Дружба играет важную роль в жизни людей.

Если ты хочешь быть хорошим другом, ты должен понимать и уважать других людей, быть общительным и добрым. И поэтому не очень просто иметь много друзей.

Ты можешь весело и интересно провести время с твоими друзьями. Ты можешь учиться, играть, гулять и просто разговаривать с ними; проводить свободное (и не только свободное) время.

У меня есть пять лучших друзей. Это Маша, Саша, Даша, Ваня и Юля.

Люди не могут жить без друзей. Без них их жизнь становится скучной и одинокой.

Настоящие друзья всегда тебе в сложной ситуации, ты можешь надеяться на них!

Доверие, уважение и доброта - самые важные качества для настоящих друзей.

There are not so many things in the world that are eternal. After all, gold, precious jewelry, exquisite clothing, expensive cars and houses - all these values ​​are false, temporary. Over time, they depreciate, break down, deteriorate, cease to be fashionable. But among the eternal, true values ​​can be called three things. This is faith, love and friendship. “A true friend is the greatest treasure”, “a faithful friend is known in need” - how often we hear these proverbs, but how rarely we think about their real meaning.
