If you want to know the Wisma Bahasa gossip, talk to Mas Sugeng because he's been here for donkey's years. In fact he's been here so long he can remember when the Wisma Bahasa was still in Jalan Cenrawasih. If you ask him to tell you stories he'll talk and talk and talk. In fact no one can talk the hind legs off a donkey as well as he can!
