I never noticed them before: the kind that never says hi to anyone.

And walks fast.

They never smile.

There used to be a very traditional older couple that would walk together every day listening to chinese radio in Mundy. I liked them and we did nod hi to each other each time. I have not seen them for a good two years I think. They had never learned english. 

There is also the skinny lady who just walks all day long not making eye contact with anyone. She is found everywhere: on austin, in Mundy and in Riverview park. She is caucasian.
