My nine year old son went to school with a hole in his sweater. The hole was from his armpit down, and it was the size of a baseball.
He didn't know he had a hole until one of his friends pointed it out during art class. Embarrassed, he wore his thick jacket for the rest of the day.
Like my wife, my son functions with linear thinking--resolve the hole in the sweater by putting on the jacket he went to school with.
Had he thought creatively, he would have asked his teacher to call his Grammy to drop off a new shirt. Or he could have also remembered that he had a shirt in his backpack from the day before.
Instead, he wore a jacket throughout the school day to avoid being embarrassed.
