The kid is not my son

Today I was driving near the intersection of Eddy and Hyde and this white van passed me with all the windows rolled down and Billie Jean by Michael Jackson playing REALLY LOUDLY, and there was a big black guy in the driver's seat who was bobbing his head energetically and singing along, and he must have noticed me looking at him because he turned his head and bobbed his head at me and waved, and I bobbed my head too and waved back, and I think that was my favorite moment of the day.
