Most just add me on a whim, never speak to me, and ignore most of my status updates. I have trust issues. I believe by not adding someone I won't endanger their feelings if they somehow come across me in the future. But I mean, you can say I'm a bad guy if you want, I get that a lot too.
You may have decided to add me based on one experience alone, I have a good side and a dark side. It takes a long time for me to call someone my friend, with ups and downs, but never giving up in the process. My approaches are different, many things will be said, conflict may arise.
