Yesterday I cried on my way to work. There was no particular reason - the tears simply started flowing because I was so tired, and I was driving past the charred remains of the burnt-down woods, and I had seen a dead fawn in the ditch, hit by a car.
I thought I had pulled myself together when I arrived at work, smiling at my co-workers and patients, talking to the guy on the phone who had fixed my machine, even making a joke and laughing.
