I remember a few years ago when I was in sixth form we had a heatwave in May and me and a few friends saw the woman who was in charge of uniform discipline (yeah, an actual thing...and this bitch used to walk around with purple hair and a scarf telling girls to remove theirs and dye their hair a 'normal' colour) telling these poor lower school boys who'd removed their
black blazers (who still had long sleeved shirts on underneath) to put them back on
They protested and said 'have you seen how hot is is? I'm sweating and so uncomfortable' and she was like 'I don't care how hot is is, put them back on'
It's primitive nonsense
