We are friends for a long time. We trust each other. We have some personal secrets. I can tell him about my troubles and he always helps me, if he can.
I'm happy to have such a good friend as Sergey.
I have many friends. I like my friends. When we gather, we play computer games, chat, make lots of noise. I like noise.
To my mind, people should have many friends as possible, because if you have not friends, you just become very dull and boring person. It is fine when you have friends, who are able to understand you and support and help in difficult situations.
