Smells. Odors. They can bring about some of our most powerful and special memories. For me it's the smell of a car shop. My grandpa has been buying wrecked cars and rebuilding them since before I was born. I remember watching him work in his shop and even helping him at times when I got older. My dad also worked down there with him. No matter where I am, passing a man on the street who is covered in car grease or sitting next to one at a restaurant, if I smell that smell all of those wonderful memories come back to me.
