It was a sunny Saturday morning in Jacksonville, and five-year-old Jake was waddling around the house in his dinosaur pajamas, dragging his stuffed T-Rex behind him. Gaby, his 18-year-old sister who was home from college for the weekend, spotted him and instantly lit up with a teasing grin.

“There’s my little baby brother!” she cooed, scooping him up like he weighed nothing.

“I’m not a baby!” Jake protested, squirming in her arms. “I’m five!”

Gaby giggled and ruffled his messy hair. “Aw, you’ll always be my baby. Look at you with your little dino, so ferocious,” she teased, playfully growling back at the stuffed toy. “Roarrrr!”

Jake tried to hold in his laugh, but a giggle slipped out. “Gaby! Stoppp!”

She plopped him down on the couch, then grabbed a juice box from the fridge. “Here you go, your royal highness,” she said, putting a bendy straw in it and handing it to him like it was a fancy drink. “Sippin’ like a boss.”

Jake took it with a pout. “You don’t treat me like this when I’m seven.”

Gaby raised an eyebrow and smirked. “Oh really? I’ll still be tucking you in and calling you ‘Jakey-wakey’ when you’re twenty-five.”

Jake groaned. “Gaaabyyy…”

She plopped next to him on the couch, wrapping an arm around his tiny shoulders. “Sorry, bud. Big sisters get automatic babying rights. You signed the contract when you were born.”

Jake leaned against her anyway, sipping his juice. “You’re so weird.”

Gaby smiled, kissing the top of his head. “And you’re my weirdo forever.”
