Now, I know that sounds funny. Let me explain. Every time I hear a commercial for "Back to School" I can actually smell a new box of crayons. LOL! That got me thinking about other smells. Think about a certain teacher and I think of the smell of those mimmeod tests she handed out. (You know you smelled the paper too.) Those are my school related odors.....but I have come to realize I have others.
Then I can also smell something and it triggers a memory.
Am I crazy, or do you also have thoughts of the past triggered by smells?

You just made me remember my junior high school history teacher, who always wore a liter of Liz Claiborne cologne every day.
