"Hey, Ferb."
Phineas sat next to his stepbrother, the thick, green leaves of the tree they were sitting under blocking out the usual summer sun. The sky portrayed such a vibrant shade of blue, and there was a cool breeze blowing through, causing the leaves of the tree to brush together in a way that almost sounded like music.
Ferb turned his head to Phineas, giving him his silent "I'm listening" look.
"I've been thinking . . . Do you think we'll ever run out of ideas?" Phineas paused, and after Ferb made no effort to reply, he continued. "I mean, so far it's only been one summer and we've already done so much. Do you think that it's possible that we're wearing out all of our good ideas before it really matters?"
Ferb shifted towards Phineas, crossing his legs and making direct eye. It does matter, his expression said. The red-headed boy shrugged, letting out a rather over exaggerated sigh.
"I know, Ferb. It matters. We're making ourselves happy, entertaining our friends . . . but don't you ever fear for the future?"
"Well," Ferb started. Phineas could already hear the sarcasm dripping from his voice (he was pretty sure he was the only one who could ever tell when Ferb was being sarcastic). "We did time travel once, and we seemed pretty well off."
Phineas chuckled at his brother. "I guess you're right. We did seem rather content with where we ended up. At least, as far as I could tell from what Future Candace and Future Mom said."
The boy then stood up from where he sat under the bright green tree and started pacing. He did this only when he was really, really pondering something, like he was then. He put his hands in his pockets, positioned his head so he was staring at his own feet, and walked back and forth from tree to fence to tree to fence and so on.
"I'm worrying too much," Phineas declared finally, stopping in front of where Ferb was still sitting cross-legged on the grass. "We're gonna be fine. Right?"
Ferb gave a small nod, and Phineas smiled. "Right," he answered himself.
He then went back to his original position, sitting next to Ferb in the shade, leaning back against the trunk of the tree.
"Well, Ferb," Phineas said, tapping a hand on his shoulder. "What are we gonna do today?"
They both laughed.
