Thermal Mates

By Nan Potts

The cold that measures records, breaks

The lows below the zero makes

And climbs to where a heatwave slakes,

The body and the mind.

Then from Fahrenheit to Centigrade

Once calculated and overlaid

In numbers temps do escalade,

Obverse sums of their mate’s.

But,

At minus forty a plan contrived

A doppelgänger is revived

Conversion as equals strived,

Asymmetry no more.
