The school I work at on occasion does activities with a local school here in Shanghai. On this day there was an art experience happening but these students had finished and had been sent back to class. Their room had 46 kids in a concrete room with a black board...and that was it. Nothing you would expect in an elementary school. No student work displayed etc. Additionally they were expected to remain quiet as there was no teacher for them for about an hour.
A colleague decided to start a sing-along with them. She started with a Chinese song she knew. She then moved into some English songs. This was their reaction to a foreign teacher in their room.

Recrop to focus on the two faces and adjust the several levels (brigtness-, contrast+, saturation+, sharpness+)

I hope you like it.
