The Turks have a wonderfully poetic phrase that translates as, “Languages cannot be learned without tongues touching.” I’d wager most travelers would agree with this sentiment, although they’re usually more focused on the tongues touching part than language acquisition.
That said, hooking up with the local flavor is beneficial for both reasons. Dating a local brings about stomach butterflies along with a bonus shot of excitement given by their fundamentally different upbringing. But the cultural and linguistic disparity is more than simply exciting — as the Turks already know, it’s the single best way to learn a language.
