  • "In the report, The Exclusion From School of Children Aged Four To Seven, Ofsted said most children 'responded well to the school's expectations', but a few found this difficult. Bad behaviour included biting other children, persistent refusal to follow instructions, swearing, running away from staff or kicking or hitting them, climbing over the school fence and throwing chairs."

  • is 'expel' now politically incorrect, or is 'exclude' a British thing?

  • it's so much creepier than 'expulsion' in this case. the long use of 'expel' within the school system has dulled its punch, whereas exclusion reads like a deliberate emotional decision to ostracize (we musn't exclude people; that's just mean); definitely not a mere punishment.
