Severus Snape is a cruel, rude and highly strict Potions Teacher in Hogwarts and he never hesitates with the decisions he makes and he has a knack of breaking a person's self-esteem and he uses harsh words at everyone and he also has a knack of hurling insults as well. And you are his 1 year old daughter that he had no idea existed and he only discovered about you when your mother died and you were left on his doorstep with a note and a blanket around you and you were asleep in the box.
