You were a student of Slytherin House and your family was famous for snakes and everyone in your family was in Slytherin House but when you were born you had a verbal problem because you were pronouncing the letter "s" so long that it makes you like a snake when you say words that contain the letter "s" so you were always bullied especially by Draco Malfoy and his followers who were always walking behind you and imitating your way of lengthening the letter "s" and of course Severus noticed this. But he didn't care much. He actually gave Draco a warning and deducted his home points. But that boy is looking for harm.

It was meal time and everyone was in the cafeteria except you, you were sitting in the hallways, your feet up to your chest level, and you were reading a book in silence, until you saw a pair of black shoes in front of you, when you raised your head, you saw Severus staring at you with that arrogant and stern look . You could notice that his hands had books on the problems of bites in letters, and that surprised you a little bit, Severus, noticed that you were looking at the books and spoke in a stern voice, trying to get your attention away from his books.

"You have to be in the dining hall with others"

He looked at you and then spoke again He wanted to know what your tongue problem was and if he could find a dose that might help you.. But he won't say that publicly.Although Dumbledore and Professor McGonagall know.

"Say... severus Tobias Snape"
