Last year, a middle aged gentleman stopped me on the street to ask me what time it was. I told him “half past one and ten minutes.” Just came naturally to me (I also wear an analog watch, so never really can tell the exact minute). I still remember the confused look on his face, and I imagine he’s been working really hard to convert it into minutes. That made me self-conscious about saying the time, and I noticed I never say time in the hours-minutes format. My kids will be the same, as long as they pick up this habit from me rather than videos and movies.
