We all desire good friends and what defines a good friend will change somewhat from person to person. As I think of this today, I can summarize this with the statement, Be the friend you desire. In other words, exhibit the behaviors towards friends that you desire in a friend. I thought a bit about this today and here's what I've come up with so far.
Listen
Attentive listening is a quality of a good friend.
Helpful
Good friends are helpful when help is needed.
Forgiving
Good friends know that we all make mistakes and good friends are forgiving.
Fun
Good friends enjoy having fun together.
Trusting
Good friends trust one another.
Loving
Good friends are loving.
Keep expectations reasonable
Be Honest
I'll return to this list soon to add more qualities.
