William surprised Mary with a beautiful proposal at Summit One Vanderbilt. After a nice dinner in the city, William brought Mary to a "work happy hour." Looking out at the Empire State Building, William admitted that there was no work event and got down on one knee. Mary was shocked and ecstatic, and through her tears, she squeaked out a "YES." William thought of everything and, as Mary turned the corner, she was surprised by their family and friends, excited to celebrate with them!
