Why Are Crabbe And Goyle Slytherins?

Why are crabbe and goyle Slytherins?

They're not really smart or cunning.

They're more like Hufflepuff. Loyal friends who always trust you and do what you want.

Is a Thestral as patronus only visible to those who saw someone die?

What does a Hogwarts student do, when he gotta go pee at night?

It's not allowed to leave the beds at night.

All professors address the students as Mr or Miss, except Dumbledore and Lupin.

All people at this post are talking about Viktor and how cool he is and how much he loves hermione, but all I can see is this guy in the last picture, smiling and thumbs up

Why does he do that?

Harry's thoughts, when he named his children

1st child (James Sirius) : I just name my kid after my dad, who was killed by the most evil wizard of all time, when I was 1 yo, because one of his best friends betrayed him...

And after my father's best friend, who was killed by his crazy cousine, who loved the man, that killed my parents....

2nd child (Albus Severus) : Albus was my headmaster, who lied my whole life to me and who put me at the door of my wicked relatives...

Snape also lied my whole life to me. He always treated me badly, I thought he hates me. He was bullied by my father when they was at school and he had a crush on my mother. He killed Albus Dumbledore and was a deatheater. The guy who killed my parents killed him too...

3rd child (Lilly Luna) : My mother was named Lilly. She's also dead. Her sister didn't talk to her, after Lilly went to Hogwarts. James, Sirius, Albus, Severus and Lilly died because of me...

And then, there's Luna... She's alive, but also a little crazy. She maybe had a crush on my wife... Her father betrayed us because of her...

What Ginny wants? Who mind? What about Remus, the other best friend of my father, who also died for me? Doesn't matter...
