Robert Irwin has shared a photo of a note he was given by a stranger on a plane.
As Robert, 15, and his family caught a flight on Father's Day in the US (June 16), a fellow passenger decided to scribble a message on a napkin and have it passed onto the Irwins.
"Our lovely flight attendant just handed us this note on our way off the plane," Robert wrote on Instagram where he shared a photo of the note.
"Little gestures like this really mean a lot. It warms my heart to see people who take a little bit of time to do something kind. Thank you Carolyn."
