Speaking of my trip home yesterday, it's always interesting to come home from China, because I get to go backwards in time. For yesterday's trip specifically, I departed Shanghai via Pudong airport at 12:20 PM on Friday. We were in the air for about eleven hours, and landed in Seattle at 9:15 AM Friday morning, 3 hours before having taken off. If you look at a map, it will become apparent that we crossed the International Date Line, which is entirely responsible for this apparent shift backwards in time. Nevertheless, it requires a conscious mental adjustment to remember that when I landed in the US, and all throughout the rest of the day yesterday, it felt like Saturday but was in fact still only Friday.
