ha-ha-ha

Two young women are smiling and laughing while looking at a phone held by the woman in the white sweater; a third woman is partially visible behind them, also smiling, in what appears to be a classroom with a green chalkboard and a clock on the wall. The woman in the white sweater repeatedly points at the phone screen while laughing, and the woman in the blue shirt smiles and looks on, with the third woman occasionally peeking into the frame.
