I hate when this happens!
The Scene: My house; I am preparing to go to the grocery store. I have my list in my hand.
Me: Oh, I wanted to make that [recipe recently seen]. I had better make sure I have all the ingredients. I will look at the recipe. It was right here in this book.
[picks up book and flips to index, looking for name of recipe]
Me: [baffled] Why, I know it was right here in this book...or, well, maybe it was this one...I was reading it recently, too...
[checks another book lying on table]
Me: Hm, not here either...oh, well maybe it was in this magazine I was reading the other night...
[flips through magazine without success]
Me: Argh! Where was that recipe?!?!?
Google! Get on this--I need to be able to do a keyword search of my brain!!!
