My favorite useless fact is that the guy who proposed modern Daylight Savings Time was an entomologist from New Zealand who wanted the extra daylight to catch bugs. That’s all.
An 11-year-old who survived the school shooting in Texas went into survival mode and put someone's blood on herself to pretend she was dead. The classmate next to her died and then saved her life. This is the kind of trauma you hear from an active war zone, not a 4th grade class.
