CAMBRIDGE, MASS. — Andrew R. Gray '20, walking down Plympton St. after his 10 a.m. lecture in Sever Hall, reportedly stopped and said hello to Samantha P. Gardner '20, an okay friend of one of his blockmates, as she passed by in the other direction.  

Onlookers’ responses to the quick exchange varied, from shock and confusion to wonder and delight. “Huh, I typically just contort my mouth in a bizarre, only partially expressive way when I pass someone I know but don’t really know on the street,” said Sarah E. Johnson '18.
