I haven't got many friends, maybe because I'm not very sociable person and prefer to spend my free time alone.
I really would like to have a true friend.
3 years ago my best friend went to Sant-Petersburg to study there and we have fallen apart, only when she comes home for a few days we go out together and chat. She is very smart, funny, curious, I always have a great time with her.
I had another friend but he went to another city too and we don't keep in touch.
However, I think I will find friends.
