Why?

What is it about me that results in me getting so frustrated or bored or disgusted with people that makes me want to remove them from my friends' list in Facebook? Why can't I just ignore them, leave them on there and get on with my life? I have removed so many people and regretted it afterwards because I've seen them and sometimes spoken to them and felt really bad about taking them off. I really wish I had never even gotten into Facebook in the first place. It is addictive and a total waste of time. I find myself writing stupid things and uploading pictures of people and places in my life that I really don't think people give a hoot about!
