Answer: When it's being 'sold' to a child. Instead it is....
Finding unphotogenic bits of fossilised oysters and belemnites on a beach followed by an ice cream from a much more picturesque cafe in a park.
Playing in a ruined castle on a headland.
Foraging fennel, elderflowers and borage.
Waiting for a train that will never come thanks to Mr. Beeching.
Popping 'Grandpa' out of bed. These flowers sure fly!
Marching along the banks of a lagoon.
And rescuing puffed out butterflies from the path.
But never,ever,ever just say 'Let's go out for a walk'. Geddit?!!
