found this one hiding in my old stories and i like it enough to share it here uwu

The tree stood tall above them, a monument to all they had done and all they had endured. In the moonlight it seemed to be bathed in silk and magic, and when the leaves rustled in the warm breeze they whispered of the upcoming adventures just around the bend. Summer was coming - the third summer since that very first idea, that wonderful rollercoaster.

They lay on their backs beneath the beckoning branches, eyes cast upwards into the vast expanse of space stretched over the earth. They could take a million rockets into those shining depths, and it would still remain an enigma at first glance. Perhaps it was that unearthly blackness, or even the stars, in all their shining glory. Even with their vast knowledge of these things they found them mysterious and awe-inspiring.

This was how Phineas and Ferb welcomed the swiftly approaching summer; with a quiet night of star-gazing.

"Do you believe in reincarnation?"

And perhaps a bit of spiritual discussion.

Ferb turned his head ever-so-slightly in the direction of his brother, who was still gazing into the night with a tiny smile on his face.

"…I don't quite know what I believe in," he replied softly. The silence between them finished the rest for him: Why do you ask?

Phineas managed to tear himself away from the sky to look over at Ferb with the most serene expression on his face. "I don't know either," he murmured, "but do you want to know what I do know?"

The leaves above rustled in an enthusiastic yes.

"I know that I've always known you," he continued almost breathlessly.

Ferb didn't need to speak. He never really needed to; Phineas spoke for him. But he decided to anyway.

"How do you mean?"

Back up to the sky went those shining blue eyes, so full of wonder and optimism. So full ofknowledge. Phineas knew the world, knew his brother, knew himself. Knew that what he said was true.

"The first time I saw you," he whispered, "you were so familiar. I knew in an instant that I was going to be your best friend and that you'd be mine. It was plain as day to me - I didn't even think about it. I recognized you. I recognized that you were mine."

Again, he looked over to Ferb, and with one look in his eyes - the same exact shade of blue, dark as the world above them - he knew that Ferb understood what he meant.

He had felt it, too.

"I've always known you," Phineas repeated. "Always. Maybe we used to be angels, or shapeless entities somewhere between planes of existence. Maybe we were gods. Or maybe reincarnation is real, and since the dawn of time, it's been you and me in some form or another."

"Or perhaps it was in the future," Ferb mused, "and we have simply moved throughout time, hand in hand."

"I like that," Phineas sighed contentedly. "All through time, forward and back. And we always found each other."

Silence returned to the air between them, broken only by the songs of the cicadas and the distant cars unfortunate enough to still be out on the road.

"That's deep," Ferb muttered after a time. And then he laughed. And, as always, Phineas laughed with him.

They laughed long after it had ceased being funny, after they'd forgotten what the joke even was. It felt good to laugh together. To be together.

When the fit subsided, Phineas turned on his side and grinned at Ferb with every ounce of affection he could muster pouring out through his eyes. "If that's how it is, in every place in time, then I haven't just known you - I always will know you."

"Leave it to the Flynn-Fletcher boys to persist for all eternity. You couldn't pry us apart with the universe's largest crowbar."

And they laughed again, all through the night, and this was how they welcomed the next summer to Danville.
