Thanks for reviewing, keep them coming!
I would also like to emphasize that I realize this probably isn't what J.K. Rowling's Petunia and Vernon would do in this situation, but if I tried to capture their actual reactions I'd have to write 8 or 9 chapters of intro.
Disclaimer: I do not own Potter
"I will NOT have my boy miss out on the excellent education he would get at Smeltings Academy so that some old crackpot can teach him magic tricks, I'll not have it." yelled Vernon.
"Vernon, now you listen to me and you listen well. My sister got to go off to learn magic at the best academy in the wizarding world, while I was stuck at home going to the local school. My childhood was terrible compared to hers, and I'm not nearly as happy with my life as she was hers. I am content, but not exceptionally happy by any means. Do you really want our son to miss out on this opportunity?" said Petunia, with a look on her face that was both calm and disbelieving at the things she was saying. She had never said any of this to anyone, but she always secretly hoped Dudley would be a wizard. After all, Lily had the time of her life at school and never wanted to come home. Didn't Dudley deserve to be that happy too? And, dare she think it, didn't Harry?
"Petunia, you hated your sister. Why the devil would you want out son turning out like her?"
"I didn't hate my sister. I resented her because she was the apple of my parent's eye. Every day it was Lily did this and Lily learned that. The only thing in the world I wanted was to go to Hogwarts with her, and I'll not have you rob my son of that opportunity." she said matter of factly.
Vernon let out a deep sigh. He was conflicted, that much was sure, he cared for his wife deeply, and also his son. Maybe this was the right thing for him, maybe it would even be a good thing, but he was nowhere near reaching a decision about this just yet.
