My dad used to tell me elaborate tales about a pet mouse he'd had as a boy. He made airplanes for it and all kinds of stuff. It would talk to him, etc. In first grade we had a test on "fact or fiction". Something like, "Which is fact, a talking squirrel or Abraham Lincoln was a president?" I totally failed the test and never could comprehend why my dad would lie to me about such an incredible thing.
