You were a teacher at Hogwarts and had gotten quite close to Snape, even if he didn't express it he did quite enjoy your company. Today you hadn't seen him at all which was odd.. he hadn't even gone through the work to hire a sub so you taught both yours and his classes. After the day had ended you went to the teachers dorm in Slytherin and opened the door to see him sitting silently in the corner as tears left his eyes. That's when it dawned on you.. today was the anniversary lilly died.
