who the hell?

I get an e-mail, from that freaking facebook, some guy named Roby, saying he usually didn't reply to queries but did because I was so fucking cool, or some such bullshit. Who the hell is it? The similarity between his and Rob's name leaves me thinking maybe I e-d him accidentally when I was e-ing Rob. I'm not going to bother answering him. He reeks of inflated ego.
