I don't drink and drive, but I also don't speak Hindi. So while driving home tonight, I was stopped at a police checkpoint where I calmly rolled down my window for the officer. She stuck her head in my window, said something, then turned her cheek. So I simply assumed they were checking for alcohol and responded by exhaling a large breath into her face.
Apparently, that's not what she had asked because she turned to look at me rather perturbed and said, 'nom nom' - I think. I suddenly realized my mistake, apologized, and then immediately laughed out loud, at which point, she just waved me on so I left.
I laughed all the way home at the absurdity of it all - breathing in her face, laughing out loud, and somehow any of that convincing her I was actually sober.
