As Robin prepares to graduate high school, and Dickerson gears up to enter her senior year in the fall, the two are trying to spend time together before they won't have the opportunity to do so.
In the meantime, the two girls will both attend prom at Robin's high school on May 30.
The sisters are working on getting the same summer job placement, Patrice Dickerson said. Robin is even joining the Dickersons on a trip to Martha's Vineyard at the end of June.
After finding out she had a sister, Jordan said she has "a different outlook on life."
"It's just one more person that I'm so close to, that I can tell everything to," she said. "She'll always be my friend, she'll always be there."
While the two girls have only known each other for five months, Patrice Dickerson said the sisters have been in "the honeymoon stage." She said she anticipates the two transitioning to a "normal sister relationship."
"They'll get into real sister issues, like borrowing clothes, and 'She can do it, why can't I?'" Dickerson's mother said. "I'm looking forward to that."
