I will always urge you to search for the good in everyone. But don’t become blind to the darkness we all have as well. Some people have been hurt severely and will bleed on other people. Some will hurt others because of what was done to them. Some will hurt others for no reason at all. If you are a mouse and you ask a snake for help, be surprised when he is willing to help you, but don’t be when he will try to eat you afterwards. Whether it’s in another person’s nature or in their nurture to see you as the enemy, there is only so much you can do to keep the peace. Try to understand where they are coming from and what it is they need. Understand that human communication is usually either an act of love or a cry for love. Have compassion. See if they want peace. If not -which is very likely- you walk away. This is their war with themselves, not yours.
