I can also manipulate a lie detector and have demonstrated such on my job and in school for the education of those who think the machine is reliable.
I've done that once. By the end of the test the polygrapher (?) was so p.o.'d he was red in the face. (and I was telling the truth on every question he asked so it was a moot point anyway)
I'm like Francois, I hate crowds. Guess that comes from dubdom. But I don't have much intuition or whatever you call it when it comes to people. So to play it safe, I just keep my mouth shut and my guard up.
