This (see the comments here) isn't the first time someone has said something like this about me (see also this and this post in which I believe I contributed some to his conclusion). I could name off a half dozen people that said something similar. I'm not saying I disagree with them. I just don't get what it is I say or do that causes people to arrive at these conclusions after a brief encounter.

About the only thing I can think of that might have given them this idea was that I explained how easy it was to get a knife through airport security (Sebastian said, "I'm glad you are on our side" after I did this). But then Uncle explained how to get a gun through which is a little more difficult but uses the same principles as I used in my knife example--so I'm not sure why I was singled out as an example.
