A widow's story
                Heather Gray (middle) goes over how to properly conduct an experiment with her children Garrett, 9, and Ava, 7, during a home school session Nov. 10, 2015, at a friend’s house in Virginia. Heather started home schooling her children at the start of this school year. Heather and her three children moved from Colorado, where her husband David was stationed at Fort Carson, earlier this year for the first time since his death. (U.S. Air Force photo/Staff Sgt.
