A rose and a carnation are two very similar things. One of them sprouts with a vibrant smooth stem, whereas the other is cursed with thorns. To Rarity, one of these flowers reminds her of a certain somepony.

Of all the stories I wrote, this is my all time favorite. Sadly, its also the least popular :(
Not exactly a shipping story, but romantic in some ways.
