I'm not sure if we become more persnickety and less tolerant (or tolerable!) as we age, or if we just have a better idea of what we want and expect in a friend, but the older I get the easier it is to recognize when a friendship is no longer working out. It's a lot like breaking up — painful but for the best. Has your bad-friendship threshold lowered with years? Do you wish it would?
