SweetmeatsBush Theatre, London★★★☆☆ THE theme of Karim Khan’s Sweetmeats, now showing at the Bush, settles on the lives of Hema and Liaquat, both in their 60s. She is of Indian origin; he Pakistani. Both live in solitude in England while consciously aging. Both suffer from deteriorating health and are culturally adrift. At a workshop designed to instil healthy living habits and combat diabetes, they meet and connect: she mostly berating him; he through a warmer, gentler response.
