Numbers

I was on the phone with a constituent the yesterday. All of the sudden she said, where did you say you went to school again, Country Day (a prestigious, local, private school)? I certainly never would have said I went there as I am not originally from the district and certainly didn't go there. What prompted this sudden interest? Apparently, I pronounced nineteen correctly when giving out a number. According to the constituent, most people don't these days, and she almost died from surprise at hearing it correctly. Randomness.
