One Day When We Were Young, Lungs is a two-hander that condenses two people's relationship over a number of years into a one-act play, although here most of the focus is on one period of their lives. A young couple (Kate O'Flynn and Alistair Cope) are shopping in IKEA one day when Man suddenly brings up the question of whether they should have a baby. Woman is completely thrown by this and so begin lengthy discussions about the pros and cons of starting a family, and apart from how the pair of them will be affected, she also keeps coming back to the social responsibility of bringing a child into an already overpopulated world.
Lungs by Duncan Macmillan is booking in repertory until the 27th of October at the Roundabout Auditorium, Shoreditch Town Hall.
Running time: 1 hour 35 minutes straight through.
