The very fabric itself...
I love Daylight Savings. I love it because it is reality manipulation. Time, in our society, is viewed as something concrete. Things start at specific times, last for specific times, and you shouldn't be late, because time is ticking away.
Then, twice a year, the government comes along and says "Hey. We can manipulate time itself! Tonight, you get exta sleep for no reason! 6 months from now, you get less sleep, for the same lack of a reason. Ha!"
And people buy it! I mean, they complain some. They say "Why is this necessary?" But that talk ends the next Tuesday or so.
