What sabotages friendship? Fear of society and family put too much pressure on young minds that you should be friends with ones who are at your level. Kids have been taught all human beings are equal but the next day when they play with a poor kid, parents would get anxious and angry.
Kids are fragile brains, they do things to fit in with popular kids, but the wrong things like abusing, stealing, or lying. It may seem petty but the adult world term these as crimes. It is a society that shapes the kids personality and brains.

The movie shows two girls who intentionally or unintentionally hurt each other with their lies. The movie ends with an idea of what goes around comes around. what we give t others comes back to us.
