He was convinced it was real.
not just education but many other things too. and it is horrifically true. spark a strong sense of vengeance in a man and he’ll show you all the scary things he can do.
Same thing happened at Heathrow a while back with a sign saying welcome to, i cant remember the name but it was a very famous London airport thats shit
