Because we have ridiculous stuff like this:
Wild Monk Parakeets flying around and hanging out at my feeder
You think you are losing it when they first appear,
they really are wild parakeets. You should see their nest over by the park.
And then your kid yells "Hey! Look at the ducks on the neighbor's roof!"
And you are all like "Whaaaaa???"
And sure enough, there they are....
On the ROOF.
It's just ridiculous.
There they were, hanging out with the sparrows and the wild parakeets....
like it was normal or something.
