"We're going to have to take that photo again. You were smiling."
"Oh." My sister had told me they didn't allow second photos, you got what you got the first time and that was it. Evidently they do allow second photos if you looked too happy and pleasant in the first one.
"Neutral expression," he said "and tilt your head back." (Not my best angle.)
My new driver's licence photo, notoriously bad, offers the world a mug shot ID. This is what I look like when I'm grim, not smiling, unhappy. I resent looking like that photo... but it's a good reminder to keep smiling in this world of grim, neutral expressions.
