Finely Structured Naturalistic Drama(Family Relations + teenage children + climactic scene) = Emotional Power

This play tells a story of 3 teenage children who have to cope on their own when mum leaves home.  The play crept up on me towards a final scene that was really moving, and all this in just over one hour.
Theatre for young people should experiment with new forms - but this play made a strong case for well-written naturalism.
