Insecurity is the certain knowledge that there is a hole in your jeans in a location that is not remotely appropriate, and that this hole is widening at a considerable rate. For added thrills, ponder the fact that it's at least six to eight hours until you can get home and change. And during this time, you'll probably have to hang out with people.

On the other hand, you can comfort yourself with the knowledge that you're in the Czech Republic, where strategically placed holes in clothing are always in fashion. Now pass me my stiletto boots, I've got a party to go to.
