Dear CC: I found this on the internet, but the poster did not name the song:

A popular song says to "make new friends/ but keep the old/one is silver/the other gold."
Friends really are treasures - as treasured as gold and silver. Some friends become
almost part of the family, often because of the length of time of that friendship Others
enter late in life but become treasured for the rol they play, even though the time
of that friendship may be short.
