Math class?

Date: 11/3/2018

It took place inside a school. The school was small having one hallway that connected to a cafeteria. The cafeteria had ceiling to floor on one wall that let in natural lighting. I was sitting with someone I knew from high school and was just discussing random topics. All of a sudden we're in a classroom sitting at these circular tables. My old math teacher comes in and starts going over some calculus problems, than she passes out a worksheet. My friend and I finished and continued talking. I took out my phone and went to type out a message to my friend. It was just asking if she was annoyed by me and if I was just wasting our time with a friendship she wasn't truly invested in ,or interested in having. As I was about to hit send she had said something (I don't remember what it was) that made me rethink it.
