Some people are like dark clouds, when they disappear, it's a brighter day. Know when its time to let go. Removing negative people from your life doesn't mean you hate them, it just means that you love yourself more.
As we experience more and more of life, and as we experience dealing with the people in our lives, we will more than likely find ourselves dealing with people who are thoughtless. Sometimes there will be people in our lives who hurt us, maybe without a second thought, because they may honestly believe that what they are doing or saying is the right thing.
