A therapist takes a 10-year-old boy into what she calls “therapy.” The young fellow is belligerently defiant toward his parents and throws titanic tantrums when things don’t go his way. At school — virtual, going on a year — he’s distractible and doesn’t finish his work without being hovered over and harangued by his mother, a tactic that frequently precipitates more belligerence and a titanic antrum.
