You can call it what you want, but almost every woman thus far on the show is way too friendly with Norman. We do know that one of the teens digs him and I do believe that that teacher was a little too close to him, and why did the camera do the close up of her hand touching his? Granted I don't think that all of the girls in the car were digging Norman romantically, but I did find it odd that they all warmed to him so quickly and even had him jump in their car, when they didn't know this guy from anyone. Perhaps you can chalk it up to teenage impulsiveness, but it didn't quite ring true for me.
I did like the scene though where they invite him to 'study' and he actually thinks he's going to study. It sounds like something I would've done.
