Sean and his mom just ogt back from one of their first time trips to New York City (NYC). During their trip they were exploring Grand Central Station when she told him a cool secret that her cousin showed her before. Under the arches of one of the walkways, if you have someone stand on the opposite side facing the wall, you can hear them even though they are far away. He tried the whispering walls with his mom and asks her to tell him her deepest secret. She said she isn't telling him anything!
