An entire subculture appears to have disappeared.

           I noticed their  absence when I returned from my absence of 13 years.
      I remember their fresh cologne on old sweat and urine. Their "devil may care" attitude.
      When I finally got a day shift, after a year and a half of driving these professional imbibers home at 2am, I noticed they were out there all day too. I drove them home for their lunch naps, and back when they woke up, for their second shifts.
       What I really noticed upon my return to Sacramento, and cab driving, is that I no longer use up a large can of Lysol in one week. I don't really have to vacuum the seats every single time. The old ones have discovered the magic of the normal: "daily bath", or: They all died. Or: now I hear they are all at the Monte Carlo.
