“My poor son,” Cassandra, Ridder’s mother, wrote in May on Facebook. “Doesn’t seem like it’s getting any better. Two teachers and a total of two students wrote in his yearbook despite Brody asking all kinds of kids to sign it.”

Rudd is not the only celebrity to find a new friend in Ridder. The Broadway cast of Dear Evan Hansen also penned their names in Ridder’s yearbook. So did high school students from all around Westminster, Colorado.
