Do you have any long distance friendships?How do you maintai

Yes,I do have such friends.
Usually,I won't bother them frequently.But it doesn't follow that we lose contact with each other.We keep in touch with each other via emails.Sometimes I will give them a call to talk about how everything is going recently.I even send them a gift sometimes to give them a surprise.Distance brings the miss from each other.They are always my friends however long the distance is.
