Despite being used by 1.24 billion people each year, traveling on the Tube in London can actually be quite lonely.

One citizen, however, is trying to change this, “You get on the Tube and it’s completely silent and it’s weird,” says Jonathan Dunne, who has started a worldwide dialogue after giving out badges (徽章) with the words “Tube chat?” last month, encouraging passengers in London to get talking to one another, “I handed out 500 badges during rush hour in a city of 8 million, expecting most of them to be thrown away, but after about 24 hours it completely snowballed,” he says, Dunne and his “Tube chat” campaign have since been reported by media across the world, seeing TV interviews in Sweden, Brazil and the UK, as well as countless website, newspaper and magazine appearances.

Although Dunne says he’s received mostly positive feedback, not everyone agrees with his idea. Londoner Brian Wilson responded with a campaign of his own, handing out 500 badges with the words “Don’t even think about it” on them, Michael Robinson, 24, a student from London, agrees, “Being on the Tube is the only peace and quiet some people get on their journeys to and from work. It doesn’t need to be spoiled by people coming up and chatting to you,” he says.

“People assume that I just walk up and talk to strangers, which I don’t, but it’s been a great way to meet people you would never have normally spoken to,” Dunne says.

So if you ever end up using public transport in the West, why not say hello to the person next to you? Just make sure to check for a badge first.
