Telling something to someone in a language which they don’t understand, interests them very much and urges them to know the meaning of it. If you wanna impress your girl friend or boy friend, you can give it a try. Just proposing in colorless words is not an interesting way to do it. You can try this, it worked for me ? . I can help you to propose in any four of these south Indian languages; Hindi (National language of India), Tamil (one of the oldest languages in the world), Telugu and Malayalam. Good luck all!
