"Grandpa" is a nostalgic country song in which the singer feels overwhelmed by the rapid changes of modern life ("It feels like this world's gone crazy") and wonders if things were really better in her grandfather's time. She asks him:
if lovers really stayed together for life
if people really always kept promises
if families really prayed together
if fathers really never abandoned their families
Poignantly, the song does not mention how her grandfather responds.
