You know that fragrance from somewhere. Like a quick breath of something past. Clean linens hanging on the line, drying in the sun? That sachet you used to keep in the top drawer? Or does it remind you of the summer you spent on the coast of Maine? It's a clean smell—sort of clear and light—and it stops time for one quick moment. It might be hard to put your finger on it exactly. And maybe it doesn't matter. All you know is that every time you walk in the room, you feel invigorated—a little fragrance pick-me-up to get you going.
