Heading to New York aboard the Acela Express, three  hours to the Big Apple. It’s work that takes me there this time, but I’ve built in a few hours to walk.

It will be the perfect way to calm down after a frenetic morning of packing, texting — and learning about last night’s Chelsea bombing. I can already imagine the relief of moving quickly down an avenue, the creative chaos of Manhattan setting the pace.

For now, there is the slightly bumpy ride of a fast-moving train, the only sounds those of keys clicking and newspapers turning. (I’m in the quiet car.)

It’s a rocking motion, and would, if I gave it half a chance, lull me to sleep.
