The people I know in happy marriages don't take the little things for granted on an ongoing basis. There is so much power in showing the person who is supposed to be the person you care about most, that they are teeth, not a dresser. You may like your dresser but you don't dust it nor pay attention to it daily. However you do show alot of attention to your teeth everyday. Brushing them atleast once a day. You don't skip brushing your teeth just because you already did it yesterday. You know that your teeth need attention everyday regardless of how good you have treated them in the past.
