Doing What Comes Naturally
With a moniker like RhymeLovingWriter (RLW) it shouldn't surprise I tend toward putting same-sounding words together when I write. I've tried my hand at free/blank verse too. Rhyme still sometimes sneaks itself in among the lines. Sometimes the material created dictates a need for rhyme (i.e. themed treasure hunts). Because I 'think' in rhyme, the tendency is strong to yield to sing-song silliness when pen meets paper. It's a natural fit for me.
Then too, when prose is called for (as in this challenge), it would be counterproductive to splash the page with Suess-i-cal mirrored magic. I've read other entries. I'm glad we have varied viewpoints. Another, who is quite comfortable with prose, will shine in a non-rhyming arena.
The end boils it down to context and conditions. Some poetic forms dictate rhyme, some forbid it, and some lie in that glorious middle ground.
Then there's the pros at Prose.
