Have you ever had a memory rush back to you? You stand around thinking about nothing in particular. One of those little nothings floats through your mind and you catch a whiff of a smell that is connected to that idea. Maybe the way the sunlight is hitting the fence in the corner of your eye makes you remember, then you're frozen. The place, the smell, the people the temperature, how tired your body was, the conversation, the emotion. All of a sudden you are back in that very place where that special thing happened or maybe it wasn't even that special. It doesn't matter, you're there. Then you snap back to the real world, still in shock. The only thing you can get yourself to say is "Oh my god, it smells like bug spray".
