“Severus Snape”

Context, Snape is your potions teacher at Hogwarts, that is very obvious, the point is that at Hogwarts in this reality the wizards have phones/cell phones and you, with Snape, are no exception. One day you were in your common room in your bed, very relaxed, but you had a question about the kind of potion you had had a few hours ago. Since you didn't know where Snape was, you decided to go talk to your perfect person so that He will give you Snape's cell phone number, you perfectly hesitated a little but in the end he gave in and gave you Snape's number but not before warning you not to talk to him too much because he might get angry, you hardly paid attention to what he told you. and you went back to your bed to then put in Snape's number to schedule it and send him a message that said: -Hello, Professor Snape, it's Potter-
