I'd defend my self but nothing more than what is necessary to get her to stop.
now I have a question for you Mentor, today I was sitting in a chair and eating cheesys, and the zipper on my jeans happened to be down. so I accidentally dropped one and it rolled though the fly and into my pants, not this got me thinking. If this happened in a public place, would you reach in to get it, leave it in and zip up, or don't even zip up just so you don't draw attention that your fly is down and you now have food in your pants?
