Later, not a single person will recall seeing the lady board the flight at Hobart Airport.

Nothing about her appearance or demeanor raises a red flag or even an eyebrow.

She is not drunk or belligerent or famous.

She is not injured, like the bespectacled hipster with his arm scaffolded in white gauze so that one hand is permanently pressed to his heart, as if he’s professing his love or honesty.

She is not frazzled, like the sweaty young mother trying to keep her grip on a slippery baby, a furious toddler, and far too much carry-on.

She is not frail, like the stooped elderly couple wearing multiple heavy layers as if they’re off to join Captain Scott’s Antarctic expedition.

She is not grumpy, like the various middle-aged people with various middle-aged things on their minds, or the flight’s only unaccompanied minor: a six-year-old forced to miss his friend’s laser-tag party because his parents’ shared custody agreement requires him to be on this flight to Sydney every Friday afternoon.

She is not chatty, like the couple so eager to share details of their holiday you can’t help but wonder if they’re working undercover for a Tasmanian state government tourism initiative.

She is not extremely pregnant like the extremely pregnant woman.

She is not extremely tall like the extremely tall guy.

She is not quivery from fear of flying or espresso or amphetamines (let’s hope not) like the jittery teen wearing an oversized hoodie over very short shorts that makes it look like she’s not wearing any pants, and someone says she’s that singer dating that actor, but someone else says no, that’s not her, I know who you mean, but that’s not her.

She is not shiny-eyed like the shiny-eyed honeymooners flying to Sydney still in their lavish bridal clothes, those crazy kids, leaving ripples of goodwill in their wake, and even eliciting a reckless offer from a couple to give up their business-class seats, which the bride and groom politely but firmly refuse, much to the couple’s relief.

The lady is not anything that anyone will later recall.
