At that point, they were both PhD students and Chun wanted to incorporate their research projects into Anna's ring.
As Chun explained, Anna's project studies the contaminants of urban billabongs (oxbow lake) which involved a lot of sediment core samples. Chun's PhD project was investigating the use of special polymers to produce hydrogen for renewable energy. One aspect of his work was making films on clear glass microscope slides. After a bit of conversation back and forth, Chun packaged up and mailed a glass slide from his own PhD work and a little chunk of basalt from Anna's research work.
Through no fault of our own; mine or Chun's ... it was a long, long wait till the package finally arrived at the post office in Williams Lake. Chun mailed his inlay material on the 15th of July. On the 13th of August we still hadn't received the package but got the happy news that Chun had just submitted his thesis! That was cause for celebration on the home front!
To this day neither I nor Chun have any idea where his package disappeared to for those 6 weeks. We were both trying to chase it down and were reaching the point of giving up on it ~ then lo and behold. . . There it was, safely delivered to our post box on September 1st. Yah! Still in time for David to complete the work on Anna's ring for Chun's planned proposal in November.
