QOTD: What Are Your Deal Breakers When Dating?

I've found that the older my girlfriends and I get, the slimmer the pickings when it comes to the dating world. This may be because as we grow, we have a more concise idea of what we want in a mate because we've had enough of what we don't want over the years. Or for some, it may also be that they don't know what they want at all! Which brings me to the Question of the Day: What are your dating deal breakers? What are the things the would absolutely stop you from dating someone and why...is it religion? Children? Future goals? Job or lack thereof?  Let me know!
