I can take apart a fifty-page agreement and find every trap in it. But sitting across from the person who wrote it, I still can't always tell what they're really after. The words on the page I've mastered; the motives behind them I'm still learning to read.
More people experience this than they realize.
You can read the document cold but you're still learning to read the people behind it.
If this sounds familiar, the Library can help you find the bigger picture.
