Our 13 yo daughter was working on a vocabulary assignment today, and this is how a conversation went...

daughter:  Man, this dictionary is lazy!

mother:  What do you mean by lazy?  How can a dictionary be lazy?

daughter:  Well, I'm looking up a word that begins with 'un', and the dictionary doesn't list it under 'un'; it makes you go find the original word for the definition.  How lazy is that?!

mother:  Honey, if the dictionary listed every single word that could take the prefix 'un', it would be so big you couldn't lift it.

daughter:  I still think it's being lazy.

mother:  Just out of curiosity, what is the word you're looking up?

daughter:  Unmotivated.

At this juncture, the two of us just cracked up laughing at the irony of it all.  It's little moments like this that make homeschooling so meaningful, don't you think?  :o)
