IE: Every Wednesday, 13-year-old Amber Opperman skyped from school using sign language with her dad who was serving overseas. Little did she know, on this Wednesday he was really in the other room waiting to surprise her. Amber, who's deaf, couldn't hold in those tears when he suddenly made his grand entrance into her classroom. Tech Sergeant, David Opperman, has been serving in the Air National Guard for 20 years. This was the first time he was deployed for so long since Amber was born.
