On the way to the park - I could've sworn a big bug flew in the open window. But I couldn't see it on the floor while driving. And it was quickly forgotten once we got to our destination.
While driving back home - I heard it. And then I saw it walk across the floor of the passenger side, fix it's wings, and then fly out the window again.
It was as though he flew in haphazardly, layed on the ground (whether napping or unconscious) for awhile, and then left again. It was a safe and clean place for him to hang out for a bit. Strange.
But then it reminded me of the part of "You've Got Mail" when Kathleen Kelly says: "Once I read a story about a butterfly in the subway, and today, I saw one. It got on at 42nd, and off at 59th, where, I assume it was going to Bloomingdales to buy a hat that will turn out to be a mistake - as almost all hats are.”
And I decided that the beetle/bug/thing was just hitching a ride because he was too lazy (or maybe tired) to go all that way alone.
