The year was 2006. The place was Honolulu, Hawaii.
For one night, two little girls who had met at a dinner cruise during their respective family vacations were inseparable.
Fast forward to 12 years later.
Brianna was flipping through old scrapbooks and watching old vacation videos on 24 November when she started wondering about her long-lost friend.
Then, an idea dawned on her.
"Wow, let's see if Twitter can find her for me..." the 19-year-old thought, before tweeting a photo of her and her 24-hour vacation BFF.
To say that Brianna's tweet exploded would be an understatement.
Her post not only caught the attention of over 100,000 Twitter users (and counting), it found its way to the very girl it was meant for.
Heidi, who had not even logged onto Twitter in years, found out about the viral post from a friend.
"The first thing I see (when logging onto Twitter) is a search party for my ass," she said.
Her response, which included a photo of her family from the same fateful night on the cruise, was priceless.
The cherry on top of a magical friendship reunion? The epic reactions from Twitter users who had become fully invested in Brianna's search.
Since finding each other, the pair have been making up for lost time by catching up on "life and school and everything"
"I honestly thought it would take at least a week to find her. The Internet is so amazing and showed me that it really is a small world after all," she added.
However, Brianna told Buzzfeed News that those expecting a face-to-face reunion shouldn't hold their breath.
"We attend college on two different sides of the country but we do plan to meet again once we get our funds together," she explained.
The Twitterverse will be patiently rooting for you two until then!
Earlier this year, an adopted Malaysian woman was able to find her biological mother after posting old photographs of her on Twitter:
