Now me: 

Oooooh - good one, I forgot about Nick's death-year!  Hmmm...too much 
of a coincidence to be a coincidence, IMO.  But the card says that 
Wright was the son of a Muggle father, so that would mean Nick was a 
Muggle...I always assumed the Hogwarts ghosts were once wizards, but 
perhaps that is an incorrect assumption??
