All are a friend but a good friend is someone, who is good and is your friend. Or, a friend who is good for you. Or a friend who treats you nicely.
Or a friend who sees good in you, even when you have doubts. Listens and understand, Sit with you for no reason other than to be with you. Calls you to hear your voice and confirm that you are well.
