Snape stood at the gate to the graveyard. This was always a difficult journey for him. She was gone and there was nothing he could do about it. All he wanted was to be able to have one more day with her. Just them. All chance of that happening had been murdered years ago.
He sighed before pushing the gate open, walking to the gravestone he knew the path to like the back of his hand.
As always when he visited, he collapsed to his knees overtaken by his insurmountable grief, tears streaming down his face, falling freely to the floor. His arms hugged the gravestone, his cheek resting against the top.
After ten minutes of sobbing, he began speaking, describing how Harry had been doing at school, how much he struggled to look the boy in the eye, and apologising for his struggle to show him any affection.
"It just hurts too much to be around him." He whispered in the darkness.
He conjured a vase of lilies and placed it at the foot of the gravestone before lifting himself from the ground, wiping his eyes and walking away. Once outside the graveyard he disapparated back to Hogsmeade.
