Saying "thank you" may be the two hardest words that friends share. We like to see ourselves as independent and not needing anyone's help. When a friend does something for us, it is difficult to humble ourselves by thanking them. Believe it or not, as strong as your need is to believe yourself independent, your friend may have an even stronger need to hear the words "thank you". Your friend may see that he is the one who is always doing the thanking and will appreciate that he is also a contributor to the friendship.
