Perry the Platypus steped out, feeling more than a little dejected, and heard the door slam shut behind him. He'd done something wrong. He didn't know what, but he'd done something. He'd gone about things in the usual way, but this time Doofenshmirtz had gotten upset, almost defensive. He'd hurt his feelings somehow. Perry sighed and started home. he had to do something. He didn't know how to make up for something when he didn't even know what he'd done, but he knew he had to do something.
Perry stood awkwardly in front of Doofenshmirtz's door again later, feeling foolish. He considered just leaving, but the door flew open before he could make up his mind, and Doofenshmirtz stared for a second.
"Perry the platypus you've already been here today. Why are you here? You can go home now." Perry grudgingly pulled his hand out from behind his back. "F-flowers?" Doofenshmirtz stammered. "For me?" Perry nodded. "I don't know what to say." The platypus removed his hat and placed it over his heart and looked up at his nemesis sincerely. "Are you apologizing? It's all right, Perry, I was just feeling a little underappreciated. You didn't have to do this. Would you like to come in?" Perry looked over his shoulder and shook his head. "Oh, okay, if you have to go. I'll see you tomorrow." Perry tipped his hat and smiled before he started away. "Thank you, Perry the Platypus."
A/n: yyyup. PerryxDoof. Because they have hinted so hard that it is, in my mind, totally canon. I hope you enjoyed it, please review :)
