All sonnets must be similar.
In that they all have fourteen lines
Though some are unfamiliar.
Unusual in their design.
As poets find new ways to say
the thoughts which they are keen to share.
They have to share them come what may.
In words they carefully prepare.
Petrarchan or perhaps English
the poets have the right to choose
to write in any way they wish.
Although the purists will refuse.
To recognise all variants.
Why should we listen to their rants
