A Small Dementor Puzzle

No: HPFGUIDX 19002


> Without reading GOF, I don't think I've seen Dementors speak; they 
apparently understand spoken English, but perhaps they don't have much 
to say.  Dumbledore tells the school, "It is not in the nature of a 
Dementor to understand pleading or excuses", which suggests, if they 
_do_ understand the language, that something like autism or Asperger's 
syndrome is their natural state of mind.  

I think they must be able to speak or communicate somehow, because 
otherwise how do Fudge and Dumbledore learn that one was trying to 
administer the kiss to Harry in PoA?  Harry was the only non-dementor 
witness to this.
