This kindergarten teacher Karen
seems to be in absolute terror while screaming for help. That is, until she notices a camera pointed towards her, and suddenly things carry on at a much lower volume.
Using the commonly taught tactic of yelling 'fire' instead of 'help' when in need of assistance from strangers, this Karen is screaming at the top of her lungs. The thing is, there is no danger whatsoever, and she is completely capable of walking away and minding her own business. The nature of the situation is unclear as well, as she seems to be in a confrontation of sorts with the woman next to her, but they are far from having a conventional argument.
One comment points out that depending on who sees this video, this Karen may go from a kindergarten teacher, to a former kindergarten teacher. At the very least, she should not be in charge of teaching young children mature problem solving.
