Remember the thrill of casually walking up to a neighbour's door, knocking on it and running away at lightning speed in a fit of giggles? An 81-year-old did just that while revisiting her old neighbourhood recently.
Olive Smyth's son Mark, who caught the whole thing on video, said his father recently died and he wanted to cheer her up, so he brought her back around the neighbourhood in Dublin where she grew up.
After telling him about playing the childhood game of knock and run as a kid, Mark told his mother she should just do it then and there.
