All men are born firstly with the instinct to protect themselves. But few grow to really love themselves, and even fewer learn to love their neighbor as themselves.
People change us. It is a rare, if not an impossible occurrence, that we come out of relationships unscathed. In our dealings with people we take something with us and we leave something behind. Some people are haunted more than others, either by the sweet perfume of another or the stink of regret.
Let them see that you trust them & let them solve their own problems, make their own decisions.Do that & they will commit their lives to you. Bully the, control them out of fear or malice or just for your own convenience, & after a while you'll have to spend all your time thinking for them, controlling them, & stifling their resentment.
