Everyday Things

While a boy and a girl are waiting at the train station, another girl sits behind them. The pair performs a backward arm movement, which she misses and goes on to board a train. Left alone they engage in a waacking exchange.
Reaching a bridge in the middle of an urban lake she realises the couple's intention and rushes back to their meeting point.
Once there, they face each other one by one as we gaze into their minds where we see the members of the pair enclosed by colourful cages.
After the single girl manages to get to them, we see all three form a dance conversation before sitting on the same side of the bench as a train passes behind them and the film ends.
