Being honest may not get you a lot of friends, but it will always get you the right ones. It's not how many friends you have it's the quality of friends you have. Fake people hate honesty. It's the lies that keep them feeling good about themselves and their lives. So share your true feelings about their actions and watch how they fade away.
