I didn't say a thing about home schooling , the point is parents , like you state yourself, spend more time "busy" or away from their children so on a hectic morning when things are all coming down at once , something as this can happen.
It's so far from premeditation , it's almost the opposite , but of course you can believe what you wish.
It's down to a disconnect , that's all. Lifestyles , personal interests , and pressures contribute to the lack of connection.
