"Tunes?" Lily called out timidly, pushing open the door to reveal her sister sitting on the bed, staring at the wall.
After a few moments, Petunia turned to look at Lily with a deadened expression. "Why Lily? Why can't you be normal? We were getting along so well, why do you insist on ruining it?"
"Oh, Tunes, I'm not doing this to be weird, but this is important to me. I wish you'd be happy for me, this is what I've always wanted. Well, not exactly, but the idea of it is."
"Well, I'm sorry, but I can't be happy for you," Petunia said softly.
Lily realized she'd get nowhere. and that she and her sister would never be close again. This was the fork in the road, and each had chosen different paths. Paths that would never again meet in the clearing.
"I'll miss you, Tunes," Lily murmured as she left the room.
Petunia waited until she heard Lily's footsteps recede to say, "I'll miss you too, Lil."
