Measure of the year

SFO terminal 3 before my flight:
I was thinking about places in our lives where we are “obliged” to spend time. Few of them being the courthouse for jury duty,the workplace, home and the DMV. Only the airport terminal seems to be a place where all of us as either(passengers/pilots/staff) have to converge before boarding our planes. Unless you work in travel, we spend just a few hours a year in the terminal. Ultimately we have little to no control over how long we spend in it, weather, scheduling and TSA permitting. We are impermanent; just ghosts in the terminal.
