Joanna
Joanna McCoy was a most unusual child, Spock observed. She was not loud and rambunctious like many human children her age and she preferred to pepper the science officers with questions whenever she could. She certainly had a very curious mind for a ten year old and Spock did his best to answer her questions as clearly as possible.
"Mr. Spock, what makes the artificial gravity?"
"Mr. Spock, how many planets have you visited?"
"Mr. Spock, is it true Vulcans live for 200 years?"
"Mr. Spock, do you like fighting with my mom?"
The last question took him aback. What had she seen in his debates with the doctor?
"I do not enjoy being at odds with Dr. McCoy," he replied slowly, "but I confess that our less hostile debates are rather intellectually stimulating and interesting."
Joanna giggled at this which puzzled Spock until she explained.
"Captain Jim was right! You guys ARE flirting! You should ask mommy out sometime."
With that she pranced away, leaving a flabbergasted Vulcan behind to marvel at the precociousness of young humans.
