Title: My Sun was Always Setting
Characters: Barbara, Susan
Summary: There's no sky like that of your childhood.
A/N: For john_amend_all, who offered the prompt of Barbara with Susan being 'alien'.
The girl was in the library again. Barbara Wright quietly opened the door. “Susan,” she called. “It’s time to go home. The building is being locked up for the night.”
Susan Foreman looked back at her with a detached, strangely dreamy look on her face. “Have you seen the sunset?” she asked.
Barbara frowned, but joined her by the window. “Very pretty,” she observed.
“The colours here are so different,” Susan said softly. “I do like the blue. But the orange of the sunset…”
Miss Wright looked askance at her faraway eyes, curious. “Yes?”
“It makes me so very homesick.”
