If you want people to stop calling you a liar, it's really simple: take pics of yourself in the classroom w/ the students. Then you post them on here. Any BS about you not supposing to take pictures will not be accepted. If you are an alpha-male-lone-wolf-what-the-fuck-ever you call yourself, then you won't let something as silly as "rules" stop you from proving yourself.
Then again, if you are full of shit, as everyone believes, then you will come up with some lame-ass excuse as to why you can't do it. Just know, if you do, no one will ever believe anything you say ever again (not that they do now, but as far as I'm concerned, it'll be the final nail in the coffin).
