I have been asked "What is a pod?"
It is a structure, that is round inside and out.
It is a structure you can put just about anywhere...backyard, side yard, garden, dock, floating on a raft, beachside, middle of the woods, field, roof top, parking lot...
You can use it if you are seeking a quiet reprieve from all the noise and commotion from everyday life, a haven of sorts to escape in.
Or, it can be a kids' clubhouse where friends gather to play dolls and apple to apples.
Perhaps for some it will simply be a folly in the garden.
