Next day, Hogwarts owl came with admission documents. Sirius filled up all forms which required general information about their background, and sent them back to Hogwarts. They then deposited the tuition fee in Hogwart's Gringotts account. Then they finally shopped for their regular clothes.
After that, for next couple of days they tried to learn Occlumency through books, which both found very tough. But they progressed slowly. Sirius tought Harry advanced Transfiguration, Charms and Defence spells he knew. It also helped, that Sirius used to be an Auror before he was sent to Azkaban.
It was a week before Hogwarts, when both decided to finish their school shopping. Harry dragged Sirius to Fluffy's Second Hand Shop, to purchase for their Hogwarts uniform, as shop lady promised a discount. However, they could not find any second hand shop for trunks in Diagon Alley, and new trunks were very expensive
"Harry I think I'll take a trip to Knockturn for trunks. There are few shops that sell old trunks there." Sirius said while handing Harry packet of their purchases.
"Okay then, I'm going to Flourish & Blotts. Will meet you later at Leaky Cauldron."
Harry pocketed shrunken bags and moved towards book store.
The 'Used books' section was at the back of the shop. She and Sirius already purchased most of their course books. Only potions book was left, as it was not available last time.
Harry moved towards Hogwarts old books section. She saw one battered looking copy of fifth years potions, but it had a lot of ink blots and its cover was also coming out. She looked around and found another copy which was in better condition and put it in her shopping basket.
She needed one more copy for Sirius. She looked on the top counter and found a fine looking copy. Just as she put her hand on it to pick it up, another hand came at the same time to pick it up.
She looked sideways at the person and could not believe it. It was dark tosser again, who was looking at her with frowning face.
She remembered his smug expression on getting that black robe. She won't lose again. This time he's going down. With determination, she immediately snatched that book.
"Hey I saw that first. Give that book back to me. Now." Tom said angrily.
"Ha..You saw this first. Whatever. It's mine now. I will win this time you Robe Stealer." Harry said with glint in her eyes.
"You" Tom looked surprised, he didn't recognise her. Then he growled " Give that back you bitch." He tried to snatch it back, but Harry hid it behind her.
"Did you just call me a bitch?" Harry said. She the looked at his face, then pointed her finger at him and said . "You are a pig faced ugliest creature on this planet. And I am buying this book. You go to hell."
She sidestepped Tom and ran towards the counter. He tried to catch her but she was faster.
She reached counter then looked back at him and smiled. Then made ' L ' sign with her finger and thumb towards him.
