For KO’s prompt, ‘all the squares’ referring to an A.A.Milne poem Lines and Squares, from which I quote these two lines:
And I keep in the squares,
And the masses of bears,
Although you can’t see squares in this photo, my camera lens is looking through square shapes in a cut glass vase at the teddy bear on my windowsill.
(This post can double as my mundane Monday photo in Lieu post too).
