I was told as a kid that people and animals 'went to be an angel' rather than 'died', so I naturally believed that all the representations of angels that I saw were actually a type of ghost.
This stayed with me as a sort of superstition, so that anyone calling a beautiful child a 'little angel' around me would be told 'No! He's not! He's NOTHING LIKE an angel!', to their great bewilderment.
Also, the sight of children in Nativity plays in angel costumes even now fills me with dread. Don't their mothers KNOW they're tempting fate!
