I left Singapore’s Changi Airport this morning after 32.5 hours of travel. Half an hour later, I arrived at the hotel where I’ll be staying for a couple days and took a shower in the pool locker room because my room wasn’t ready. My primary objective for the afternoon was to stay outside as much as possible in order to keep myself awake and to let natural melatonin do its thing.

Immediately upon leaving the airport, I realized a year away means a lot in terms of memory. For example, I’d forgotten that they drive on the left side of the road here, a legacy of British colonialism. I forgot that no one knows how to walk in a straight line, that people actually wait for the crosswalk light to change before crossing the street, and that escalators are for standing (strictly on the left, of course). Additionally, I forgot that you tap your subway card on the way in and on the way out to calculate the fare and I forgot the subway map altogether.

So many people smoke cigarettes, which I’d also forgotten, and it’s gross. And yet, I knew exactly where to find the closest money changer and where to get a new SIM card. I remembered the location of certain stores in a mall I used to frequent and was able to recognize new ones.

It’s weird that I was gone for a year . . . and it’s weird that I was gone for only a year.

I felt somewhat similarly in Rochester this summer. There were certain things about driving around town that I’d just forgotten. I’d forgotten how certain neighborhoods blend into each other and the names of different streets that I used to know. It’s unsettling that after spending so much of my life in that one place, a lot of it was gone, replaced by new pertinent information like all the local and express stops on the 4, 5, 6 trains in New York.

I expect that it’s going to be the same in Singapore for a little while. There’s definitely some adjusting to do, but it feels good to back.
