As they began to make their way through the streets of towns and cities across the country on Friday morning, singing songs and holding hands, the school children and their long-suffering parents and teachers protesting again climate change resembled a rather long walking bus.
By mid-afternoon, it had become something rather more chaotic.
Labelled “a strike” by the BBC, the Government called the sight of thousands of children skipping school plain “truancy”.
Theresa May condemned it, with the Prime Minister’s deputy official spokesman saying: “It is important to recognise that disruption increases teachers’ workloads and wastes lesson time that teachers have carefully prepared for.
“That time is crucial for young people precisely so that they can develop into top scientists, engineers and advocates that we need to tackle this problem.”
Labour leader Jeremy Corbyn, saw it differently, saying it was “inspiring to see them making their voice heard”. Pupils could be heard chanting his name throughout the day.
In London, the march quickly descended into anarchy as teenage girls ran topless through Westminster with slogans inked across their skin, while others smashed up signs and groups of students drank and danced across the Parliament Square lawn, which some were quick to point out had only just been replanted after being all but destroyed during last summer’s heatwave.
