Chitungwiza, Zimbabwe - Pikai sometimes drops in at Clay's home round the corner for a bite to eat and a chat, and Pikai returns the favour by letting his neighbour collect water from his tap that seldom runs dry. The odd thing about this neighbourly sharing is that 10 months ago Pikai - not his real name - was among a mob of vigilantes of President Robert Mugabe's ZANU(PF) party flailing with sticks and heavy electric cables at Clay's back, because he was a supporter of the then opposition Movement for Democratic Change.
