After sharing a bedroom for 18 years, the Shine triplets are finally preparing to spend some time away from each other once college starts in the fall.

The seniors -- Nicole, Lindsay and Kristen -- are one of two sets of triplets graduating from Eastport-South Manor Junior-Senior High School in Manorville this year.

The siblings, along with the rest of the Eastport-South Manor Class of 2017, celebrated their prom at Flowerfield Celebrations in St. James on Tuesday.

The Shine triplets have been inseparable their whole lives, and the fall semester of college will be the first time the three have ever spent significant time apart.

Nicole Shine will attend Marist College in September, while Lindsay will attend Adelphi and Kristen will attend Farmingdale University.

Close quarters have never been a problem for the trio, who run in the same friend circles and have competed together in soccer and track and field.

“We do everything in threes,” Nicole said.

“We’re a package deal,” Kristen added.

And that mentality isn't completely going away just because they're finally going to have different addresses.

"We’re all gonna probably text each other 24/7 still,” Lindsay said.

Meanwhile, the Suarez triplets – Marissa, Christopher and Matthew, all 17 – are experiencing a similar situation, albeit with a slightly different outlook.

"We want to see what’s it’s like to be separated,” said Christopher, who won a state volleyball title with his brother as seniors. “We’ve been together our whole lives.”

The siblings are looking to attend separate colleges in the fall, although their individual choices are still up in the air.

But after sharing birthday parties and countless other rites like prom night, a little space is a welcome development. 

“I know I’ll miss them, but at the same time I’m like, ‘Finally, I can be more independent,’” Marissa said. “There’s a party up inside my head right now.”
