I am puttering around near the reference book section of the B&N when I hear this exchange.

Daughter: You need a book of words that are the same as other words. A book of cinnamon.
Mom: Ah.. okay... this?
Daughter: No that's a dictionary you need a book of cinnamon.. hmm.. they should have it!
I decided to step in here.
Me: Excuse me I think you need a thesaurus. Here, it's on the top shelf. I'll get you one.
Daughter: Ah, no that is not what we need. That is not a book of cinnamons.
Me: No, I am certain this is what you need. By the way the word you are looking for is synonym.
Daughter: Ugh! No! You don't even know cinnamon is a word that means other words!? I don't think you are helping us.
I sighed and walked off.
I hear a quiet voice on the other side of a book isle saying "That just happened".
