i managed to convince a couple people and as far as i know they still believe that im blind reason was....boredom it took everything in me not to laugh my ass off when there waveing there hand in front of my eyes and throwing thing trying to make me flinch almost lost it but it ended with them feeling guilty for messing with me and me about to cry with laughter....im glad i never had to go back there dont think i could pull it off twice still cant believe it worked the first time.
