Old schoolmates

I walked past some warehouse-looking building trying to dodge people in a dense crowd. I looked to my left to the warehouse's platform and there I saw two people, a brother and a sister, who had been in my class four years ago. I was just thinking how much they had changed from those days. The girl had grown bitchy.

I spotted their mother and kept on going.

Analysis: Hmm... can't say anything about this with so much confidence; I recognized the people but my comparing of their current ways of life to their old ones were both accurate and imagined. It's too messed up memory to find any patterns.
