There are a number of characters from dysfunctional family backgrounds.
Dumbledore, whose father murdered three teenagers for harming his daughter, and who may have accidentally killed his sister.
Snape, whose father and mother fought continuously and lived in poverty.
Harry, whose parents were murdered and who grew up with people who hated him.
Tom Riddle, an orphan from an inbred, insane, violent family.
Neville, whose parents were tortured into insanity, and who was raised by a grandmother who belittled his intelligence and talent.
Ron, The youngest and least promising son, whose parents wanted a daughter.
Hermione, whose parents were dentists.
All these people struggled with their origins, and most turned out OK because they chose to be decent people. Tom was offered the same opportunities, but chose a life of vengeance.
I thought is was rather touching that Harry offers Tom one last chance at redemption, but Tom is so far gone he basically destroys himself rather than listen.
It appears you've had the same sort of experience with dentists that I have ...
Brilliant!
Very Rowling-esque humor, might I add.

Yeah, you've gotta watch out for those dentists!
