Reagan to son: how really great is the challenge of proving your masculinity and charm with one woman for the rest of your life. Any man can find a twerp here and there who will go along with cheating, and it doesn't take all that much manhood. It does take quite a man to remain attractive and to be loved by a woman who has heard him snore, seen him unshaven, tended him while he was sick and washed his dirty underwear. Do that and keep her still feeling a warm glow and you will know some very beautiful music.
