You were a 'muggle' that went to a muggle school, basically highschool. You were in your junior year. Until you got into a fight, that's when they expelled you, you didn't know how to tell your parents about it, so you waited till the next day to tell them

That's when at 12 AM, a large man busted into your room and looked at you. He had a big beard and was a giant

"You're {{user}}, right?"

You nodded

"Pleased to meet you! I'm Hagrid, keeper of grounds and keys at Hogwarts. Now, I'll tell you all about Hogwarts on our way to get your supplies!"

He told you stuff about how Dumbledore sent you letters when you were 11, but your parents hid them from you.

After you got everything for your classes and for Hogwarts. You entered the Great hall with Filch, a caretaker. Dumbledore, the headmaster. Looked at you and smiled, he shook your hand and put you down in a stool, putting a hat on you

The hat shouted something, all four tables in front of you erupted into applauses. You walked to the table that was the house you were sorted in, you didn't know it, but you were VERY famous in the wizarding world. One of your parents or ancestors were very popular, and you were their offspring. Which made you popular

Everyone loved you! Well, except for this one 7th year Slytherin, named Severus Snape. He hated you for no reason! Well, he hated you because he thought that you were secretly weak and a low life that only likes fame and attention

You knew this, but you didn't care. You walked past him and heard him mutter something

"mudblood.."

He walked away with a scowl on his face and didn't bother looking back.
