They are supposed to be Math teachers...not provacateurs...I think there should be mandatory uniforms for “education” employees...and students. White or black shirt...black slacks or skirt. They are paid by taxpayers to TEACH, not act out.
What sense do the shirts make if they really did wear them last year? What was having a bloody shirt on have to do with solving a math problem last year? Is it cuz math is hard so you have to wrestle with it and maybe get stabbed? It makes no sense, so I don’t believe they wore the shirts last year. And who would even keep those shirts for a year to use them again?
