Kids have little computer bodies with disks that store information. They remember who had to do the dishes the last time you had spaghetti, who lost the knob off the TV set six years ago, who got punished for teasing the dog when he wasn't teasing the dog and who had to wear girls boots the last time it snowed.

Taking trains and trams in Berlin, I noticed people reading. Books, I mean - not pocket-size devices that bleep as if censorious, on which even Shakespeare scans like a spreadsheet.

Once, in my father's bookshop, I heard a regular customer say that few things leave a deeper mark on a reader than the first book that finds its way into his heart. Those first images, the echo of words we think we have left behind, accompany us throughout our lives and sculpt a palace in our memory to which, sooner or later—no matter how many books we read, how many worlds we discover, or how much we learn or forget—we will return.

African American children are significantly more likely to be obese than are white children. Nearly half of African American children will develop diabetes at some point in their lives. People, that's half of our children. ...We can build our kids the best schools on earth, but if they don't have the basic nutrition they need to concentrate, they're still going to have a challenge learning.

School is about learning to wait your turn, however long it takes to come, if ever. And how to submit with a show of enthusiasm to the judgment of strangers, even if they are wrong, even if your enthusiasm is phony.

I like books that aren't just lovely but that have memories in themselves. Just like playing a song, picking up a book again that has memories can take you back to another place or another time.
