People come into your life for a reason; the negative people usually are there to teach you what you don’t want to become, treat you how you don’t want to be treated, and to show you what you don’t deserve. Embrace them, let them teach you, and then let them go. ~ Unknown.
And these people are part of your lessons which will be repeated until learned. When these people are no longer in your life because you’ve let them go, your lessons will be complete. Let go and be happy because you deserve nothing less.
