About a year ago, two sisters at a local Virginia Beach tea shop on a beautiful summer afternoon sipping delicious bubble tea, sharing laughs and enjoying each other's company, unsure of when they might see each other again. Both sisters the Navy in January 2014, leaving for basic training only two weeks apart. Since then, they assigned to different duty stations, making it difficult to find time to see each other.
