“Those feelings of envy are familiar to many of us. We see our children accomplishing things that we’ve always been afraid to try, or we give them opportunities that we never had, and we find ourselves feeling jealousy mixed with our pride, or we feel resentful when they take it all for granted.”
—Ruth Davidson Bell (20th century)
