The only two characters of any consequence besides Mike and Patience, to appear in "His Robot Girlfriend" are Mike's two children-- Harriet and Lucas. I initially patterned them after my own two kids, just as I had patterned Mike after myself. My son is in the Jr. ROTC, so I made Lucas a soldier. My daughter likes animals and Harriet has many animals. My daughter is older than my son, and Harriet is older than Mike. From this brief basis, I expanded the characters as I wrote, so in the end, they didn't bear much similarity to the real people.
