Seriously. If you wanted to have a conversation with me and it was something other than "what do you do?" I don't think I'd know what to tell you. If I'm not at work, I'm taking care of my baby, and you probably don't want to hear about poopy diapers...
The real answer here is you probably wouldn't want to have a conversation with me anyway.
