She walked into the living room, where the afternoon sun streamed through the window. She sat down, pulling her legs up to her chest, and stared out. The world felt different now. Less sharp, perhaps. More complicated.

She remembered the way the air had felt on graduation night, charged with excitement and fear. She thought of her best friend, Amy, who was also receiving the invite. She had not spoken to her in a very long time.
