You’re in the Tenderloin, all digressive conversation and hoit and toit, then you lay down the law and say it’s time for upscale boilermakers. Next thing you know you’re in Lower Haight listening to Nine Inch Nails with a vegan hamwich and you’re not even a vegan.  Everyone’s wearing funny hats.  And worse, they all look to be 18.  How nice, this late summer/early autumn evening!
