Friendship, my thoughts

Very recently, a friend got upset with me. It really was for no reason and yet I still feel the upset inside. Part of my problem is that I often feel someone is a friend that really has not thought of me as one. Part of the problem is that when I consider someone a friend, I feel a closeness and devotion to the relationship that few people today ever experience. Maybe being a friend is old fashion, maybe it take too much effort in this high tech busy world. What ever, I am grateful to this forum that lets me vent when I need to.
