After my grandpa had cataracts removed and new plastic lenses in his eyes he was a bit confused by his vision. One night he noticed the full moon through the trees while looking out the window and started excitedly telling me there was a UFO in the sky. So I ran to the window to see for myself and seeing nothing unusual I was puzzled and kept asking "Where, I don't see it!" Until finally realizing he was pointing at the moon. We began arguing and I got exasperated and ran outside to get a clear view. Then I began excitedly pouting at the moon and shouting, " You're right, it's a UFO!" And " you gotta see this!" And enticing him to join me on the driveway. So he rushes out and looks up at his UFO and then dejectedly say, "Oh, it's just the moon." Me, "are you sure, Daddy? It could be aliens..." And I busted up laughing "aliens, aliens! They're coming!" Grandpa shuffled back inside, very disappointed and annoyed by my laughter and teasing. I miss that guy and the fun I had pranking him. Making fake snails he tried to kill, fake flowers out of playdo he swore were real, and stealing a treasured piece of oak I refused to give back only to return as Christmas gift after I turned it into a snack tray. But the alien bit had me laughing my ass off. I think a great many UFO sighting are mistaken Identity or just unidentified stuff. The hoaxes are easy. Include real stuff with fabricated stuff and people judge the whole thing authentic. Real snail shells on silicone body and Grandpa will stomp them, never questioning how the snail leaves no slime trail and is on a porch in hundred degree dry summer heat. Fake flower on a real twig but no one questions how a flower grows on a dry twig. Real navy ship but photos are always out of focus. You get the idea.
