It's not just Cag. I've seen you do the same thing to Lisa, and Lily, and countless others. You surround them like jackals and pick at them until they leave. Is this what you do in real life? Are your social skills so twisted that you believe this is how people relate to each other? If so I pity you.
I used to try and do this too, because I was unhappy and insecure, but now that I've grown as a person I see the error of my ways and try to be nice to everyone now that im nearing my middle ages. :)
