It has often been said that the secret to a happy marriage is to concern yourself with your spouse's (girlfriend's, boyfriend's, lover's) happiness more than your own. Last week, Scott Schuman (The Sartorialist) wrote a lovely piece called A Graceful Man, A Gentleman. If you haven't read it, please do. This is perhaps the sweetest description of how to treat the person you love.
