I think a friend is someone who is close to you. I have two best friends who know me very well. We always support each other and spend a lot of time together. I think friends never get bored of each other. We do not have a lot in common because we have different hobbies and we have different tastes in music, for example, Ann plays the violin and likes classical music, but Olga prefers to listen to pop music. I don’t like music at all. I prefer reading. We are so different, but I think still we are best friends.

I am a very sociable person and I have a lot of friends. I don’t think I have one or two best friends, because all of them are close to me. All my friends are very supportive and I think I can rely on all of them in any situation. My friends are different, but we have a lot in common. For example, my friends Adiya, Assiya and Alikhan love drawing and swimming as I do. We have a strong bond because we have known each other since kindergarten. I think childhood friendship lasts forever. I am happy to have such good friends and we always support and help each other.

1. ...... has two best friends
