I chose a Thrust stage because I think this really gives the audience the oppurtunity to be a part of the play. It gives different perspectives and angles, offering sides of the story otherwise left unexplored.

The Thust stage gives us the useful advantage of a stage wall. This provides the actors with a security, it is a place to wait and perform any off scene parts. i.e The Headmaster talking through the door. The Thrust also allowed more freedom with design, the stage is narrow and thin, mimicking that of a store room, but as it is surrounded on three sides, it is still intimate with the audience and very visible. Opposed to if it was a Prosenium Arch, where some audience members may feel far away and excluded from the drama.
Lighting:
The plays stage directions mention a window, which, at the beginning, has it's blind drawn. So at the start the lighting would be rather dim, warm colours, reflecting on the early morning light and the dusty wood of the stage. As the play progresses, the light should become brighter, and then darker at the end. The corners of the room and the back of the stage would be dull as the play is realism and these places wouldn't be well lit.
However, if there are any monolouges or climax's, dramatic lighting should be used to have a circle of attention on the person or object at hand. All lighting should come from directly above to avoid hitting an audience member.
