Sighs at having to explain. Rhymes don't have to be exact. You can rhyme by using syllables, which is how 'coast' and 'know' rhyme. They both share the 'o' sound. Also, you must be mispronouncing 'bad/plaid', because I can't figure out how you think those two words don't rhyme. Please stop swaying the votes. That's not suppossed to be allowed. Thank you.
