The action begins promisingly up in Delilah's bedroom, where she and three friends are chatting about High School Musical and the latest mobile phones.

Here, as throughout the play, Reiss perfectly skewers the playground politics and casualty cruelty of teenage girls, who find everything a giggle except their own lives.

It's when we meet Delilah's parents, Nick and Vicky, still at each other's throats after an affair with the boss led to him losing his job, that the trouble begins.

Their bitter rows over everything from tea and coffee to the remote control never quite convince, and there's a frustrating lack of spark between the pair.

The set-up doesn't seem to have moved on from the world of 70s suburban sitcoms, with Nick painted as the bumbling but loveable father and Vicky as the capable but undervalued wife.

Much of the comedy derives from the idea the youngsters are often much more grown up than the adults, but this is done none too subtly.

Delilah is called on to act as a marriage counsellor for her parents, who ignore her own problems, and is left cringing along with the audience as Nick jokes uncomfortably about Vicky's supposed affair with the lodger Daniel.

Daniel (James McArdle) and Delilah's (Shannon Tarbet) relationship is convincingly developed and there's an edgy chemistry between the impressive young actors.

The whole thing's cleverly staged, with the cramped rooms capturing the claustrophobic feel of family life, and there are some nice touches such as when Delilah's friends burst out of the fridge like a mini-girl band while Vicky continues her daily trudge in the kitchen.

Ultimately it's all a little predictable and blunt around the edges, but the ending's convincing and is the one moment where you're really kept guessing.

Reiss certainly shows promise as a playwright but you can't help feeling this could have benefited from a bit more work and a lighter touch, which she'll surely develop given time.
