Social Networking

When I told my previous boss that I planned to work in a library, he was surprised. He kept asking me how I was going to deal with the public since he knew I didn't talk a lot. I told him that I can deal with people within defined chunks of time and I am very successful at it. And I am! I provide excellent customer service and I make sure to give each person my full attention when we are engaged. HOWEVER, the need to socialize with big batches of people has not surfaced. I keep wondering if there is something wrong with me because I don't want to Twitter or because I don't have a FB account but I figure to each his own.
