During her art class last evening, the girl who was sitting next to her was holding her phone open under her desk and texting while pretending to be drawing the assignment. The room was dark, so she probably thought she was being extremely sneaky.
Sara: It must be pretty hard to draw while you’re doing that.
Girl, turning her head very slowly until she was looking at Sara: Who are you, my mother?
Sara: No. If I was your mother you’d have manners.
