All it would take is for my elementary teacher to say, "I'm going to be passing out BOOK ORDERS later. . ." and I'd spring into MODEL STUDENT MODE. For those that might not know, book orders were sheets of microthin tissue paper (or so it seemed) covered with write-ups on kids books that you could order to be delivered right to school. There was always a 3X10 inch (vertical) order blank that you had to cut off and fill out.
Some of the greatest days of my elementary "career" were on BOOK ORDER days. . . . and the day when the books actually arrived. . . . damn. That was like Christmas, at school, with no tree, and no HardRock, Coco, or Joe.
