Aplomb means “poise.” Ironically, Dictionary.com says
it’s from the French à plomb, “according to the plummet,
i.e., straight up and down, vertical position.”
That fits this poem perfectly!
We’re on vacation at the coast.
Our daughter thinks a photo post
Of all the family would be fine.
We storm the beach and form a line.
The camera’s on a tripod stand
So we can set the timer. And…
Nobody saw that seagull flyin’
In behind our clueless line.
The camera caught our lost aplomb.
It really was a photobomb!
