overall i'd say this is a good start off... the first sentence is excellent, very attention grabbing. there were some lines in the descriptions that didnt quite make sense. also i got very confused when Courtney all of a sudden mentioned her ADHD. she said that she had gone off on a tangent but i personally didn't see the bathroom thing as a tangent at all. she didn't seem to go off on tangents until AFTER she mentioned the adhd. also i would recommend formatting each chapter into separate chapters here on fictionpress. even thought this one chapter isnt that long the various chapters are still enough to be confusing because they end up introducing so many ideas and characters. one reason this is especially true is because the story makes a sudden switch between background description to in the present narration. the switch may come across better if it comes as a new chapter.
overall i find this very interesting. im surprised you haven't gotten more reviews on this yet but then again i know how that one works. i;d recommend reformatting the chapters and i'll try to keep up on the story as you update. and please check out my new story (Un)Predictable, a return review would be much appreciated.
