You know, only good friends will tell you that you have something stuck in your teeth. Why is that? Is it that your friends know that the long-term benefit of knowing is worth the short-term embarrassment? Whatever the reason, friendship is something we should cherish. True friends don't come along very often so, when they do, we need to treasure and protect them. So, how do you know if someone's a true friend? Well, I guess if they tell you that you have something stuck in your teeth they've passed the test. Just kidding. You can tell a true friend by the way they treat you and by the way they make you feel when you're around them. So, call a friend and take them to lunch to show that you value their friendship. If they live out of town, at least call them or send a card to show that you care.
