One is single
On it's own
One is separate
All alone
Solo
'Un' in French
In Spanish, 'uno'

One has no partner
One has no pair
One needs no sofa
Only a chair
One is good at solitaire

One may be me
One may be you
But one is definitely not two
One might feel isolated
Sometimes lonely or frustrated

One next to one reads as eleven
1 + 1 + 1 + 1 + 1 + 1 + 1 = 7
One stands proud as a number
Shaped like a dead straight cucumber

One is not even
One is odd
One is a sole pea in a pod
One is detached
One is unique
One may be labelled a bit of a freak

One doesn't ride a tandem
One rides a bike
One is independent and does what one likes
One is high performing, top of the charts
You are my special one who's captured my heart

One is sometimes sad
One is frequently fun
So don't take it away
Because then...
There'll be none
