Sometimes, say, when we’re on the Tube, and I want to tell my wife something but I don’t want anybody around me to know what I’ve said, I tell her in Hindi. (She’s from India before you get too puzzled).

Now my Hindi is poor to the point of being atrocious (although it’s probably better than yours) but I can usually get my point across. Can’t understand a word she says in reply but I can make my own point.

The thing is, I often forget that this language I’m speaking in isn’t actually the secret language between me and my beloved that I seem to think it is. I absent-mindedly assume nobody else understands it. Even in India I still have to stop myself saying, in Hindi, something that is intended for her ears only.

The day will come when I say something unflattering about somebody who is within earshot and they’ll understand exactly what I said. I’ll let you know what happened. If they allow me to continue living (I say some nasty things at times…)
