When the sun rises on the horizon, you begin to smell the day: breakfast cooking in the kitchen, bath soap and shampoo in the shower, someone's cologne, leather shoes newly polished, the fumes of a car revving in the garage.

When the sun sinks on the horizon, you begin to smell the night: a bonfire or scented candles, a grill, the scent of sweat, detergent in the sink, fresh bed sheets.
