[Origin: Latin crepusculum, from creper dusky.]
“The Arcadian hated this time of day. That crepuscular transition between the dying day and the not-yet-born night. It was the heavy trudge home, the missed opportunities of the day, the optimism that had arrived with morning now transformed into failure and sadness. Or maybe it was just him. Maybe everyone else liked it. Thought it contained the possibility of fun, adventure. Looked forward to seeing what the night brought.
Maybe.” – The Doll’s House, Tania Carver.
