• To my mind all people want to have  good friends and those who are lucky do have  them. To have a good friend you should be ready to do your best to make a good friend yourself. You should be ready not only to get something from your friend but first of all to try to give the best you have to your friend. When we make friends we should treat them in the way we would like them to treat us. We should help friends at any time only then we may expect they will do the same when you need it. We can make friends at school, in a sport club, during some trip and so on.All people need friends. You may write to one another if you live far, tell each other secrets, fears, worries, trust one another, help one another, forgive one another. Friendship is lovely! It is something which one should never lose.
To my mind the most important feeling that exists between friends is trust. 
• Sometimes friends quarrel as they can have different opinions or discuss some
problems and have different points of view, but they shouldn't criticize each other. Friends quarrel actually, because we are all human beings who have our own minds and souls which may be different from each other. We may argue about certain things but that's, in my opinion, is good because you get to know each other a lot deeper.  Respect and tolerance are also very important in friendship. 
• I'm happy to have lots of friends. Some of them are very close, some are 
less.  To conclude friendship is very important for people. It makes  life interesting and enjoyable. They are rich who have true friends, says a proverb and it's impossible not to agree with it.
