A/N: Hey! Thanks so much for the reviews to EnergeticBullet, Rorscarch, Sabrina Kelly and jolleIQ! I'm very sorry if I didn't mention someone; it's just, there has been a huge mess with reviews here apparently. Some of them just seemed to vanish.
Anyway, hope you all enjoy this one!
I don't own Phineas and Ferb.

What is a kiss?

A kiss is the perfect gift. Something you give, but don't lose anything at the same time. A kiss is a secret, something that is known and experienced by only two people. A kiss is a way to make time stop and the world disappear for a couple of seconds.

Finally, a kiss is a confession; a way to express thousands of words. It's amazing how each and every one of them passes a different message. If there were two people who knew something about that, they were Phineas and Isabella.

Their relationship didn't change much over the years, they shared very similar feelings to those when they were younger. Support, care, empathy... They were familiar with all of them. The difference was, what was once expressed through a smile or a hug, became partly replaced by kisses; but they meant the same.

Numerous times Phineas found Isabella sitting at the kitchen table, her head rested in her hands, exhausted and listless. He would always help her up, gently embrace her and give her a long, comforting kiss. It was just like saying: "Don't worry, I'm always there when you need it."

Isabella often found Phineas late in the evening, hunched over his desk, redrawing the same blueprints over again. She always watched in silence for a while, leaning against the doorframe, only to finally embrace him from behind and press her lips to his. "I'm proud of you," she was saying through it. "I love seeing your passion."

Coutless times when they wanted to make up, they would stand for a while before each other, uncertain of what to do. Cautiously brushing each other's arms or cheeks, they would finally fall into a tight hug and a long, slow kiss, embraced by perfect silence. "Just a while longer. It was terrible without you," it said.

Each kiss was specific for various kinds of situations and, the thing they realised later, they were never about themselves. They were always about the other person. And they always meant something different.

Coming back from work. "Eight hours really is a long time."

Waking up. "Can't wait to share another day with you."

Going to sleep. "I'm happy you're beside me."

Each and every one of them. "Only with you and nobody else."

That's why Phineas and Isabella always felt this slight thrill as they leaned in towards each other. They knew that in just a moment...

... they would be told something completely new.

Thanks for reading and please review! I don't know if I'll update anything before my birthday, but either way, see ya in a couple of days, guys!
