When my daughter was 3 she suddenly became very interested in the moon, so we let her stay up a little late so we could all go outside and look at the beautiful full moon for a few nights in a row. Sometime later she was again up past her bedtime, so before we put her to bed we went outside to look at the now 1/2 moon. She saw the half-moon, flung herself to her knees on the ground and began frantically rustling through the grass crying "Mommy! Daddy! The moon is broken! We have to find the other piece!" It took quite awhile to convince our disconsolate daughter that the moon was indeed not broken.
