And to cap it all ...
It is not the fault of our television: there is no evidence that Polish children are copying actors in Grange Hill or Hollyoaks. The reason is more straightforward.
Poland's ministry of education has introduced compulsory school uniforms for all children for the first time. However, local companies which make uniforms say they will be unable to fill all their orders by the start of next term because most of their staff have left for more lucrative jobs in the UK.
"I'd be happy to take on even 50 new workers," said Jacek Parol, owner of Parol Fashion. "I have to produce 20,000 uniforms, but I can't find the people to get it done."
There is an upside to the labour shortage. Many boys will be delighted that they can continue to go to school in jeans and trainers.
