Moi? Social Butterfly?

I've never been the type to be constantly having plans and running from social engagement to social engagement. But this week I am. Yesterday it reached the point where I had to fire up my Outlook calendar to write everything down, lest I stand somebody up. I wonder how people who really ARE social butterfly types keep track of everything. It feels so weird to be this type of person. Not in a bad way, just in an unfamiliar way. It's kind of fun, though I have a feeling by the weekend I'll be exhausted.
