It's probably not the lesson we're supposed to learn, but CitySeen sometimes wishes we had the kind of evening A Fai has - between finishing work and getting back home, A Fai somehow manages to have three potential sexual encounters with different women. But the A Fai CitySeen is referring to is fictitious. He is the central character in an interactive educational flash game found on the Aids Concern website. 'The game started out [as a cartoon] in our printed publication, targeting [men] as part of our sex industry outreach programme,' explained Aids Concern chief executive Graham Smith. But it was the interactive version of A Fai, apparently, that has really taken off as an outreach tool. 'We've had pretty good feedback from people,' Mr Smith said. The game can be found by following the links from www.aidsconcern.org.hk . Just don't let the boss catch you playing the game.
