Flat

My mother just asked me, with quite some annoyance in her voice, if I know what ‘flat’ means. This in the context of a failing to follow some exact instructions with respect to placing a zip bag full of bolognaise sauce into the freezer.

I responded:

“An object with a high aspect ratio which is substantially parallel to a surface which itself is substantially perpendicular to the local force of gravity”

With a sigh she gave up and I was saved from further unnecessary torture.
