Writer-performer Kristen Thomson swaps between eerily shapeless masks to deliver monologues from a precocious 12-year-old girl hiding from the fallout of her parents’ divorce, her stepmother Lesley and the wise Eastern European school janitor. Initially the theatricality of the masks dictates the tone, and there’s a sense of potential tragedy in the theatre. But no, this is a straightforward family drama, with a final coda about seeing the self in one’s own sadness that sums up just how unnecessary all those masks and costume changes were to a play that doesn’t move out of the suburban doldrums.
