So THAT'S why Dumbledore wanted Barty Crouch Sr to have a drink

[Phyllis]

<snipping Kneasy's terrific poem>  I didn't pick up on this either, but 
like Judy, I wasn't really focusing on why a 150 year old man didn't 
currently have a love life, particularly when his energies were being 
completely channelled into fighting Voldemort.  I also don't think 
Dumbledore had to be in love with Grindlewald in a sexual way to have 
had the strong relationship that was described in DH.

But at least we now have answer as to why, in an interview years ago, 
Jo wouldn't answer the question of whether any of the Hogwarts teachers 
were married, saying: "That information is sort of restricted."
