Yeah I know , I was just being a smartass . But if your native language is English you probably won ' t have too many issues travelling through any city in Europe , North America , Oceania , India , South East Asia or Southern Africa . If your first language is Dutch , for example , you ' re basically screwed outside of the Netherlands and the whiter parts of South Africa if you can ' t speak another language . English is an official language or the Lingua Franca in so many places that you can comfortably travel extensively without ever learning a single word of another language . <| sep |> Yes , I ' d like to know too . For a friend . <| sep |> Your ignorance for the acronym for double penetration doesn ' t mean it doesn ' t exist .
