Umbridge's truth spell

Everyone was sitting in the great hall whispering to each other about what they had been summoned for. They had all been called here during the middle of class and were told that they would get detention and a loss of house points if they didn't attend.

"QUIET!" yelled Umbridge after everyone settled down. "I have this spell that I am going to put on everyone in this room that causes everyone to share a secret that they have never told anyone before."

At this everyone started shouting, causing Umbridge to let off a loud bang with her wand.

"You will ALL have this spell cast on you or I will personally see to it that you are given veritaserum in order to see what you are hiding. Now, Fac tibi secreta quaeque" (Let you show your deepest secrets).

Immediately chaos started. Everyone started shouting out their secrets for the world to hear. The most noticeable ones being:

Pansy Parkinson: "I only like Draco for his money. Other than that I despise him."

Lavender Brown: "I think Professor Snape is sexy and mysterious."

Ginny Weasley: "I've had 7 boyfriends."

Draco Malfoy: "I spend an hour getting ready in the bathroom every morning making sure that I look as good as I do."

Ron Weasley: "I've always been jealous of Harry."

Hermione Granger: "My favorite book series is Twilight by Stephanie Meyer and I think that Edward Cullen is amazing."

Harry Potter: "My relatives forced me to sleep in the cupboard under the stairs until I got my first Hogwarts letter and they only gave me my cousin's second bedroom because they thought someone was watching the house."

Severus Snape: "I love Lily Potter and have done so since we were 10 years old."

Minerva McGonagall: "I MADE OUT WITH YOU-KNOW-WHO IN OUR FIFTH YEAR!"

At that, everyone stopped shouting and turned to stare at the cat animagus. Then the shouting restarted, except that this time the majority of the people in the great hall said the same thing.

"WHAT THE FUCK!"

(A.N. I know that McGonagall was born 9 years after Riddle but it didn't fit the plot. Sorry.)
