Users and Takers are a bummer but a part of life. Lower your expectations and you'll never be disappointed with the negative aspects of human nature. Stay true to your goodness anyway. Good actions manifest into good lives.
I'm done wasting my time on people who don't care another person feels. I will personally take that silence as betrayal. Or honestly that I hate you for the rest of my life kind of thing. And that is why I say nothing, its the only thing I can do.
