When the wire hands free devices came out, I didn't see them in Indonesia, but on a visa run to Singapore, I saw some dude who was acting crazy, talking to himself in the airport. Then he turned around and had a wire hanging out of his ear.I got in a taxi and there was this crazy-looking lady talking away with no one in the car. She had a hands free wire, too.I knew this woman who liked to pray in tongues when she was jogging, but she was afraid people would think she's crazy. An easy solution is to put a fake hands free device in your ear and let people think you are talking on the phone in a foreign language
