I've been on a bit of a Cara Bastone Audible Original kick (no Kindle copy). This is included in Plus, exclusive to Audible. Graphic audio/Full cast. 

I was a psych major, took social psychology, and we had some interesting activities, but no assignment like this (although there was some romance involved in that class. Ironically we broke and and he married a different gal from the class). 

While listening - I noted a few things I wanted to remember in my review. The word "scowl" (#4 hates that word) and "preternatural" (Hubs said it wasn't that common, it's been in a LOT). MCM says something about being "immune to sugar, needs a lot to get a rush" ... I feel that. Mention of Fitbit, getting in steps. A scene where they are drinking, cute drunk conversation, she decides to just sleep there on the floor. Cute in the story ... in real life though? Being so sloshed you have to crash where you are at? I mean it's better than trying to drive home of course, but ... I've got some strong negative feelings about this, and this had ironic timing. Had to build a wall to not let the association ruin the book for me (personal issues). 

Examining of love/relationships ... some sweet, some painful/dysfunctional, the innocence of young love, one lesbian couple (they were one of the super sweet ones). Again, some individual issues that affect enjoyment some ..
