I was at a client's once and their young daughter around 5 or 6 was having a fit in the late afternoon, wanted some candy and the mom said no that it will ruin her dinner. She kept pouting and whining... then said mom can I have some OJ? Of course, mom said yes. I didn't have the heart to tell her she just got played by her daughter who needed a sugar fix.
