Lily and Snape lay next to each other on the grass the summer after their second year at Hogwarts talking. They did that a lot. Just talked.
"Sev?" Lily asked that day.
"Yeah, Lil?"
"Will we be friends forever?"
Snape laughed at that. "Of course, Lily. We'll always be friends."
"Always," she replied. "That's such a romantic word. I really do like it.
Always."
