Friends are forever. When you meet a group of like minded people, you tend to share a good rapport with them. But, there is only one who gets extremely close to you. In a group, you cannot be close to everyone. Even theorists have said that in a group, proximity is less so, getting along with everyone is not possible. There will only be one or two friends out of the group who would be very special to you. You usually call these close ones as your best friends.
