Sonnet- Sonnet Needs Rhymes

Can you a Sonnet write without its rhyme? Now people want the modern verse that's free; As ideas get stuck and cramped with time, A Sonnet's like leafless branches of tree! A Sonnet's great for men who rhyme too well; Its beauty lives in metre, rhythm, rhyme; Yet, it can never run into 'pel-mel'; The sonneteer can write in any clime. Why abhor rhymes and not a Sonnet write? Each genre has its rules to comply with; Why sleep all day and stay awake all night? Rhyme-play is done by Kindergarden kith! Why ridicule something you can't do well, Much things are done by practice, Sonnets tell.
