Groups of two are called a pair
and sometimes a couple, and in verse a couplet

Two is a beautiful number full of symmetry
And the wholeness of love

One by itself and plus one is the magical
connection of friendship

Addition makes for strange bedfellows and unwelcome crowds;
let’s just leave us alone together

Even is fair and fair is better said twice
for thrice would just be too much (overkill)

But two is not too of anything; it is
the warmth of company and the smile of one child

The most important things are twofold with us
and we must have one heart because we need another’s too

For balance, the dual strains but holds, sustains
yin pulls yang and tight embrace joins old and new

Division is eternally sad but easier to withstand if
there’s no remainder and you have someone else there

And finally two can multiply if they work hand in hand
to avoid the sting of desperate isolation

You can’t play paddy cake by yourself but it’s ok to try
You have two hands and along comes a partner
