A new stalker. goodie, goodie! I was getting bored with the last pseudo skeptic anyway. I don’t even remember his name. 😳

”In my professional world....” Thats gold, Jerry, gold! 
By the way, your moniker is eerily similar to roberttcan, another pseudo skeptic here a couple years ago. Any relation? As in the same person! This is too weird! 😩
Maybe I am, maybe I am not, maybe I am just here to trigger the Pet Audio Rock dude. The universe is so complex, perhaps we will never know will we. Just remember, my words are but a conduit to aid you in making yourself look less relevant than I ever could.
