On the very same day that I ordered an iPad 2, I went shopping to buy myself a letter opener. I like to cover all my bases.

I've used Twitter now and again to try to figure something out; it's an amazing resource. But I think you have to use it judiciously: it's a self-selected group, so it's important not to start thinking of it as the whole world.

I have no idea how to get in touch with anyone anymore. Everyone, it seems, has a home phone, a cell phone, a regular e-mail account, a Facebook account, a Twitter account, and a Web site. Some of them also have a Google Voice number. There are the sentimental few who still have fax machines.

When you're researching you're learning. When you're writing, you're teaching.

I love tearing things out of the ground. I love digging and discarding. I love pruning. In fact, I love pruning so much that I once gave myself carpal-tunnel syndrome because I attacked a trumpet vine with so much dedication.

Everything rational and sensible abandons me when I try to throw out photographs. Time and time again, I hold one over a wastebasket, and then find it impossible to release my fingers and let the picture drop and disappear.

In my perfect world, we would establish perhaps four national zoos of unimpeachable quality and close the rest of them.
