On my walk through the neighborhood today I saw this on top of a low stone wall.
Yes, a tiny oasis. I pointed it out to the tall person and asked if it was real or just a mirage. He smiled and told me it was real. He explained that a mirage is a naturally occurring optical phenomenon in which light rays are bent to produce a displaced image of distant objects.
Hmm. It’s easy to become confused in an urban desert when you are tired and thirsty. I didn’t notice any camels though.
