It was the end of the summer, and Stan was the king of crappy parties. The town's favorite twins were going back to California, so of course the old man would throw a party in their honor. Most of the people of Gravity Falls had become quite fond of the kids, so the whole town showed up; even those who disliked the pair of kids showed up, if only just to party.

People were milling about, laughing loudly and sloshing the spiked drinks all over the grass. The kids behind the party sat at a picnic table, drinking punch and just enjoying each other's company.

"I guess this doubles as a birthday party," Dipper says.

"I guess it does. Do you think we should have told Soos and Stan?" Mabel asks.

"Well, they went through all this trouble anyways, why bother them with more?" Dipper asks.

"True. All we really need is each other, right, bro? Let's make a toast."

"Let's toast. To us, the newly promoted teens. Happy birthday, Mabe."

"Happy birthday, Dip. To us—long live the mystery twins!" Mabel yells, thrusting her cup against Dipper's, spilling punch all over the both of them. They laugh, and Dipper almost pees his pants when Soos startles them by saying, "Hey, it's you guys' birthdays? This calls for a celebration!"

Without waiting for an answer, he waddles up to the outdoor stage set up for the high school bands to play on, and grabs the mic, saying, "Hey doods, it happens to be the little people's birthday today!" Everyone turns and looks at him, and he in turn points at the pair, sitting at the table. Dipper's face is bright pink, and Mabel is eating up the attention. Soos starts counting: "1, 2, 3."

"Happy birthday to you," they all chorus. Dipper pulls his hat over his face.

"Happy birthday to you," the crowd sings again. Mabel blushes and sets her cup down.

"Happy birthday dear baby Pines kids," they sing. Dipper and Mabel look at each other and start laughing.

"Happy birthday to you," they finish, somebody throwing a cup at them. The cup hits Dipper on the head, bouncing off his head onto the table then rolling off. Mabel stands up, steps on the bench and climbs onto the table, yelling, "Thank you! Thank you all!" Dipper quickly pulls her down, blushing.

"Let's go get some more punch," he mumbles. They walk over to the table full of snacks and the punch bowl, and Mabel slowly starts ladling out punch for the both of them while chatting up the soon to be freshmen of Gravity Falls. While he stands there listening to Mabel's awful attempts to make a summer romance work, suddenly he has arms around him and hair in his face. Since the sun was going down, he couldn't tell the color of the hair or anything. He staggered at the shock, and heard a familiar laugh behind him.

"Happy birthday, you dork," Wendy said, pulling her arms off his eyes and away from around him. Shivering at the loss of her body heat around him in the chilling summer night, he turns around. They're close enough that he can smell her perfume and see the gloss of her chapstick on her lips, reflecting off the sunset behind him. She's wearing a flowy yellow top with a pink smiley face on it, with a brown belt and white shorts. She looks different like this, her hair flowing down into her face and brushing off her newly acquired glasses, which she had only gotten a week ago. Dipper rather liked her in glasses; he felt they reflected the intelligence her close friends knew she had. He also had somewhat of a glasses kink, as weird as it was.

"Thanks, Wen," he said, shrugging his shoulders out for a hug. Wendy concedes and throws her arms around his neck, squeezing him tight.

She lets go and says, "You should have told me it was you guys' birthdays today, I would have gotten you something. Now it's too late to go out and buy something and you guys leave tomorrow."

"Good. I wouldn't want you to waste your money, on me anyways." Dipper replies, blushing from the intensity of the hug. (He doesn't realize Mabel has ceased flirting behind him and is now watching the exchange quietly, mouthing only the words 'kiss him' very exaggeratedly to Wendy, pointing at her lips and making a duck face.)

"Well, it wouldn't be a waste, Dipper. It's for you, after all," she says, fidgeting with her glasses.

"Awh, Wen. Really though, don't waste money on me." he says. Before she can reply, Manly Dan staggers near, yelling, "Wendy! Time to go!" It's obvious he doesn't know where she is, and that will work to her advantage. She sighs.

"I guess this is goodbye, then," she says. She grabs a napkin from behind him off the table and a sharpie from her back pocket, scribbling on a napkin. She shoves it into his hand.

"My number," she says. "For, uh, after you leave." She's acting so awkward about their goodbye that it makes Dipper smile.

"Thanks, Wendy. I- uh, I'm really gonna miss you a lot," he stammers.

"Wendy!" Manly Dan yells.

"I'll miss you too, Dipper." She pulls him into another huge hug, and when she pulls away, she leans in and quickly kisses him on the cheek. She then goes and hugs Mabel, saying, "Get my number from Dipper, okay? I'll miss you," and runs into the crowd, hair flowing behind her, and then as fast as she was there she's gone, like the smell of rain or the dew on grass.
