Who is the happy little person?

A few weeks ago, I was walking down the hall in our building, when I ran into a woman who (I hope) lives on our hall. She looked at me, said “happy little person” and walked through the door into (I hope) her apartment. I was a little confused, but proceeded into the elevator and forgot about it. The other day, I ran into the same woman in the elevator, who again looked at me and said “happy little person.” I wondered if perhaps this was just an expression she used, but when the elevator stopped and someone else got on, she just said “hello.” I guess she recognized me.

I guess it’s possible I have really bad hearing comprehension, and in fact she said something entirely different and less eccentric. Or maybe I just look like a happy little person to her. Even though I am a good foot taller than she was.
