I carried him in my body for nine months and barely had him out for a year and now he's... he's grown. He's a grown man and I didn't get to know him growing up. I didn't get to see him grow, teach him how to tie his shoes, or ride a bike or argue with him over eating his vetables.
Petunia and Vernon treated him like shit. I bet they didn't praise him for anything, I wonder if it was even them who taught him how to tie his shoes.
