Jennifer Barclay, 24, of Scotland, filmed her granddad, Robert, 87, for a number of weeks and captured his sweet reactions to her arriving at his house.
"I try to visit him once a week," Barclay told "Good Morning America." "On a normal visit, we have a cup of tea and a catch up. I just filmed him because I loved his reaction to seeing me."
Barclay said her granddad lives with her grandmother Mary, his wife of 60 years. On Dec. 14, she uploaded footage to Twitter of her grandad's reactions to seeing her to put a smile on people's faces.
The video has nearly 8 million views.
Barclay has since created an Instagram account to share her grandfather's adventures: Instagram @the.grandad.diaries.
