- A true friend gives more than he or she takes.
- If you have a "friend" who refuses to give, you need to take off.
That's it. If you find yourself giving and giving and giving and being drained and drained and drained of your life blood, then you're dealing with a vampire. Stop giving. Stop the bleeding. Practice some good old fashioned Stewardship of Love and move on. Even a werewolf or a zombie would be an improvement.
