This is often not about labels (though for some people it might be) and self-fulfilling prophecies. I am not afraid of human contact, I do it well, I even enjoy it, but I don't always want to do it. Plus, what I do in my free time is my own business. So, if I don't want to go to social events, I won't go to social events. Period. I also see no reason why I should have to justify my choice. The only justification is "because that's what I want to do". If that's not good enough, too bad! What are you going to do, sue me for "selfishly refusing to meet people in my spare time"? I also find people who bike across the Alps in their free time weird, but it's their choice, and it makes them happy -- live and let live!
