I'm sorry if this has been covered in the past, but I would like to 
know if any of you have a theory on why Umbridge hated and picked on 
Trelawny?  Trelawny mentioned that  Seers have been persecuted for years, 
but why? Was Trelawny considered part human because of her gift? I would 
say no, but I don't understand why DU went after her. 
Please let me know.
