Friendship is very good. Unfortunately, in FB there is no category for "Good Friends" or "Friends with whom you want to communicate more" . When the number of my friends have become more than 500, I realized that half of them I don't know well. With someone I stopped to chat, who turned out to be a fake. with someone I have not found a common language or interests. So I the New year almost all removed. Because I was very confused in the data, please excuse me if I accidentally delete a contact good friends.
