For Writers of Original Fiction

If I could make a suggestion - you may want to have the main character noticing actions of the second character without being able to properly analyze them. For example: Christine keeps noticing that Abigails' eyes have been very red lately. She recommends a good concealer. In this way, you can exemplify not only that Abigail has been crying often, but also that Christine is too tied up in her own life to think there's anything wrong.
