I'm currently married to a Chinese born wife who has lived in the US for the past 15 years, but spent most of that time in academia with other foreign born academics. She had developed a habit of saying "BE CAREFUL!" very loudly whenever I was driving and something unexpected happened in traffic. I was patient at first, hoping that she would come to understand that I am quite careful (I'm a bit of a stereotypical asian driver myself) but one day, I snapped at her when the car ahead of me abruptly braked to a stop, then backed towards me to parallel park in a spot they'd spotted last moment.

We did talk about it, but whenever we argue, it seems that she thinks I'm lying when I tell her that saying "Be careful!" in that context sounds like an admonishment.
