"Booth!" Brennan calls. "I've found something." She waits until he walks over form down the aisle and then lifts up the puzzle she'd come across. On its cover is a tiger standing proudly in the mist of a jungle setting.

Booth shakes his head. He takes the box from her and returns it to its place on the shelf. "No."

"Why not?"

"It's advanced. And Parker didn't like the last one he was given, anyway. He said it was boring."

"Boring? Puzzles are fun." Brennan blinks in confusion.

Booth smiles. "For Parker, apparently not so much."

"Well," she says, "how about that?"

"That? Seriously? That's…really not appropriate, Bones! What are you thinking? No. What was I thinking bringing you along?"

She shrugs. "You said you hadn't been able to go to the shops yet to get Parker a birthday present and since we were low on cases at the Jeffersonian…"

"Thank you, Bones, for that. I needed a reminder of my turn to complete insanity. Remind me never to take you shopping again. Ever."

"Booth! I'm just trying to help."

"I know. Sorry," he says, shaking his head. "Just…try to help less maybe?"

"If you didn't want my help, you shouldn't have invited me along."

They stare at each other in deathly silence, only to be interrupted by a young boy running past with a miniature train under one arm.

"How about one of those?" Brennan asks meekly.

Booth glances at the train, assessing it. He smiles. "That could work. I think he'd like that."

"Well, good. I think they're in the next aisle down."

Together, they begin the search for a train. When they find one, Booth nods at it. "You pick which one."

Brennan, smiling, reaches for the closest one: a red one. "How's this?"

"Perfect," Booth replies, not taking his eyes from hers. "Just perfect."
