Some people care. Some people don't. Those that don't give a damn about you or your life should really just stay where they are and not intrude. If I don't care about you, you won't see me in your life. You'll know I care because I do participate in your life.
Ya know though, if I don't give a damn, I just stay away. I don't hang out. I don't put up false fronts; smiling at your face and then shoving a dagger in your back when you turn around, enjoying your misery, pain, heartache, or sadness.
I hope there comes a day when I no longer know such people.
