I have to admit a weakness for nostalgic childhood songs. As my mother and I say, “we sing off- key, but we remember all the words.”
One of my favorites is this round:
Make new friends, but keep the old.
One is silver but the other gold.
All my life I have taken pleasure in adding to my friends far more often than subtracting any, and in introducing new friends to old. And I think the same rule should apply to reading – and rereading – good books.
