Survived a 30-hour shift; the 4 a.m. vending machine hummed in B-flat

Not the big thing I meant to show, but the texture: at 4 a.m. the vending machine in the residents' lounge hums a steady B-flat, and I matched my breathing to it until my coffee finished brewing. The coffee was terrible, which somehow made the whole night feel honest. Small win, but I'll take it.
