Codi and Hallie are obviously very similar in that they are sisters so their upbringing was very similar. Both girls are around six feet tall and very good looking with dark hair and eyes. They both have the same family structure even though both girls interpret it differently, but they do both have a sister a father and sadly a mother who died when they were very young.
Codi and Hallie have more differences than similarities though. Codi has a very different personality she is far more dependent on others where as Hallie tends to rely on herself for what she needs. the girls also took very different but still vaguely similar choices in careers. Codi became a doctor and Hallie became what is basically a plant doctor, but Codi was never able to cope with the problems of being demanded on because she was never able to depend on herself she didn't feel confident on having other people depend on her. Hallie is also much more stable than her older sister she is very confident in who she is and what she wants to do.
Although Hallie and Codi are both sisters they are both very different in personality, job, and stability. Though they are very similar in that they look alike and they have the same raising.
