The Open Book

There lies an open book upon my table
And with one glance, to read it, I am able.
But with a single look, no book is truly comprehended.
To understand, a few more looks are highly recommended.
Now, some may say "You never really understand a book."
And so it is with people--You can read them if you look,
But with one look you cannot learn their secrets, held for ages.
Countless secrets, buried deep inside their many pages.
