Hi, I was just wondering... There were a these people playing a game where you use a quarter and flick it across a table and it hits the other person's knuckle and start to bleed. These people were playing this game and the quarter hit someone and then flew off the table and hit me (my arm)....can I get anything from this (if there was blood on the coin and I...touch a cut I have or my mouth... or something like that ) or am i just paranoid? this is really bothering me thanks, Pseudonym
