I am interested in your theories here...
On page 33 of OOTP, Aunt Petunia, Dudley, Harry and Vernon are discussing the attack by the Dementors in the alley...
Dudley is trying to explain what happened and Aunt Petunia says "what sort of things did you hear popkin?"
Harry is then thinking "what would spoiled, pampered, bullying Dudley have been forced to hear?"
And this has been bugging me for ages now!!
Does anyone have any ideas on this?
