@thesurveillanceshow: A nursing home security camera captures the most heartwarming moment when a Navy serviceman surprises his grandmother who has dementia. Hidden behind a piano, the grandson emerges and begins singing 'You Are My Sunshine' - her favorite song. Watch as recognition slowly floods her face and clarity returns. For precious minutes, love defeats the fog of dementia as she becomes fully present with her grandson. Have you experienced a similar moment with a loved one? Share your story in the comments below.
