If your child’s school picture is pretty good but not great, and you send it back in on “retake day,” the photographers intuitively know that they are dealing with Psycho Obsessive Mom.
So they will take (according to Mack) not one, not two, not three, but five photos of your child, until they know they have one that will meet with your approval.
Take THAT, children with mediocre school pictures and easy-going mothers.
