Non veni pacem mittere, sed gladium.
A Millennial tango. It reminds me of when I was in 7th or 8th grade back in the mid-50s. We'd be lined up ready to move from one classroom to another (students moved then not the teachers) when a number (always the same ones) boys started this autistic pushing and shoving even though the classroom door was still closed. Mindless testosterone fueled insanity only extinguished by a burly teacher vocal intercession. The only difference is we got over it by high school, but now it's still rampant in 40 year olds.
40 year olds with a headache and a bloody nose.
Wednesdays are like that.
Looks brutally efficient. It must a German subway train.
