That is a downright awful story.  :(  I am SO 
sorry to hear it.  All I can do is hope that it 
doesn't sour you on all the rest of the great 
people in this hobby, and that, as others have 
said here, the forces of karma eventually take 
their toll.

Oddly enough, I met a couple of my best friends in 
the hobby after being sniped by 'em.  But stealing 
a cel out from under a friend is just so wrong I 
don't have words for it.  :P

(Well, okay, I did steal a truly awe-inspiring 
Hotsuma cel out from under Laura.  But that was 
because I wanted to make her mourn "missing it"... 
right up until Christmas.  *evil grin*)

Anyway, if you'll let us know which anime and 
character(s) The Cel contained, I at least will 
keep an eye out for another one for ya... I love 
having a mission!  ^_^
