Okay, lesson time, children. Get out your notebooks and write this down. There will be many tests on it later in life.
There are two types of people in the world: Those who will do things for you because they love you and have a kind heart, and those who will do them so that they can hold them over you forever and make judgments about you. When you discover that a friend or family member who you thought was the first type of person is actually the second type, it hurts...badly.
How can you tell the difference?
Despite the clear distinctions I have just drawn, it is not always easy to tell the two types apart, particularly if you have self-esteem issues. Believe me, though, it's a skill worth acquiring, because type one people will help you to become the person you truly want to be. Type two people will push you to become the person they truly want you to be.
It isn't necessary to avoid type two people entirely; Just recognize them for who they are, try not to have too many of them in your inner circle, and only call upon them for help as a last resort.
The lesson is now over. I would now normally give each of you a cookie, but because of the growing childhood obesity epidemic, federal law now mandates that we give out slices of low-fat government cheese instead. Enjoy.
