Heartbreak Rhyme

Alright, listen up, you big dummy! This ain't your grandma's happy poem. It starts like the classic 'Roses are red' thing, right? You know, the one people use for cheesy Valentine's cards. But then BAM! It hits you with 'My heart is dead' and 'I'm such a fool.' See? It's like, 'Haha, NOT!' It takes a sweet, simple rhyme and turns it into a sad, regretful one. You probably thought it was going to be funny, huh? You always think things are funny when they're not, don't you?
