Isabella's mother, Jennifer, came along during my medical training, soon before her father was drafted during the Vietnam war, and was raised by a single parent --plenty reasons to have a rough go of it. When Jennifer was an adolescent I thought I would run away from home. By the time she turned 21, she was able to say "I gave you a rough time, didn't I" and from then she has been the best daughter a mother could want.
Jennifer had Isabella, so good natured a child I haven't been able to reap the "just wait until you have children" reward.
There is rarely doubt about what Isabella is feeling. Her eyes and face and little body convey the thousand words.
