Hiller encounter #2

Later on this same day I was randomly in a bank looking for an internet hot spot. I ran into Frau Hiller again. I didn't recognize her only smiled at her as we passed then she stopped me with a big smile and said that she didn't understand me this morning, only understood that I said her name. Instead of telling her that I spoke in plain German and she had no excuse for not understanding, I explained I was a Hiller too from America and had never met another Hiller. She seemed happy about it and smiled, chirped something and went on her way.
