On Professor Sinistra's other side was the sallow-faced, hook-nosed, greasy-haired Potions Master, Snape--Harry's least favorite person at Hogwarts. Harry's loathing of Snape was only matched by Snape's hatred of him, a hatred which had, if possible, intensified last year, when Harry and helped Sirius escape right under Snape's overlarge nose--Snape and Sirius had been enemies since their own school days.
~Goblet of Fire, Ch. 12 "The Triwizard Tournament"
It's been a while since we had a short one... I doubt many people even remember this quote unless they've reread the books just as much as I have.
Every time I read this part, I get really mad at Harry. And if I'm alone while I read it, I actually talk to the page, and say "Shut up, Potter. He's my favorite person in Hogwarts!"
And when it first introduces Snape to the scene, as always, I do a little fangirl squee on the inside and sometimes kiss the page. If I'm alone. But, just OMR, Snape has some pretty dramatic intros. *Swoon*
