The day dragged on, and Severus couldn't get the events on the night before and the morning out of his head. All he wanted to do was forget what he saw and how angry it had made him.
Thinking is own wife couldn't handle a boggart, but instead let it terrify her, was almost more than he could bear.
Severus sighed with relief when the last bell of the day rang and was more grateful than normal that Minerva let him live out of Hogwarts because of his marriage.
He wasn't happy to go home to an empty flat, though.
