"Super sigh," Gretta yawned, stretched, and continued mumbling to herself as people pushed past her, never really coming from the same direction. "Geeze, everyone here is like an ant. Hmm, not really, actually. Ants are more organized, these people would be a whole swarm of mosquitoes or flies, something like that. Though I don't think anyone here would feed off of garbage or suck blood. But saying that means I'm taking my simile all too literal, but aren't similes supposed to be literal? Or am I thinking of idioms? No, wait, idioms are weird confusing sayings, so similes would be..."
Losing sight of her reasoning, Gretta became quiet. Soon, however, her silence was broken with a cry of dismay; while talking to herself she had also been moving with the current of the surrounding population. "How could I be so obtuse!" she cursed herself, quickly trying to peek over the crowd and get a general understanding of where she was. After a minute, she deduced that she was near security line for departing passengers. And after another minute, recognized a course to bring her back to the baggage claim.
"Hopefully I didn't leave whomever is picking me up waiting for long," thinking this, she made her way back to the revolving conveyor belt and luggage.
