Someone's wife found the group chat. It was called "Neighborhood Dads." There were nine members. The last message was a Google Maps screenshot with a pin on the school. Sent at 2:47pm on a Thursday with the caption "she parks near the oak tree FYI."
The resulting conversation between that couple apparently lasted four hours and involved at least two phones being thrown. The group chat was renamed to "Youth Soccer Coordination" the next morning. None of their kids play soccer.
