I AM FEELING like an intruder. I came to see a beautiful 400-year-old church in Moldova, somehow built with neither nails nor mortar. The church is stunning, the peaceful grounds neatly groomed. Flowers bloom everywhere. White doves flit around the roof.

I AM PHOTOGRAPHING inhabitants of a dog shelter high on a hill overlooking Dubrovnik, Croatia. The setting is stupendous. I don’t understand why this land hasn’t been appropriated for luxury condos or a beautiful hotel.

I AM DRIVING to the Cape Cross seal colony on the Skeleton Coast in Namibia. This desolate, windswept stretch of sand and driftwood is aptly named. Remains of shipwrecks litter the beach, or sway in the rough surf, too treacherous for a salvage operation, left to slowly rust and rot, waiting to be claimed by the pounding waves.

I AM HEADING to the airport in Oaxaca, Mexico with my taxi driver Oscar, a big burly man who smells of cigarettes and speaks very little English. It is 3 o’clock in the morning.

FLYING: 1. If you don’t know what PreCheck is, you shouldn’t be in the line. 2. If you don’t know how to flush it, you’re not allowed to use it. 3. If you’re not going to drink it, don’t order it. 4. Never order red drinks on an airplane. 5. Control your children.

I AM MEDITATING in Chiang Mai, Thailand. I arrived a few minutes late. The traffic was terrible and the tuk-tuk driver let me off at the wrong corner of temple Wat Suan Dok. I quickly take a seat in a plastic chair in the meditation room. I am the subject of disapproving glances from everybody there. I smile weakly.

I AM LOOKING at the skeleton of a 3’6” tall woman on display in a glass case in the Mutter Museum in Philadelphia. Mary Ashberry is her name, dead in childbirth, the year 1856, long before the antibiotics that could have saved her were discovered. Her baby’s cracked, broken skull lies at her feet, a tiny piece of a tiny being.

I AM LISTENING to a story a pilot is telling me. I had heard it before from flight attendants, but I didn’t quite believe it. I assumed the tale had been embellished with typical flight attendant flair for drama, part exaggeration, part urban legend. The captain assures me it is true as he was there, a hapless eyewitness to the escapade.

I AM SITTING in the gatehouse area, waiting for my airplane to arrive. It will be here ‘any minute’, it is ‘on the ground’. These are the stock answers I always get when I ask gate agents about the arrival of the inbound aircraft. I think these are vague, rote answers, taught to them in gate agent training.

I AM LISTENING to Taka explain all sorts of interesting things on this tour he is leading deep into the backstreets of Osaka. His tour will show the hidden, the shady, the shoddy, the seamy side of Osaka that tourists never see, the covert side of this big, bustling city founded 2500 years ago.
