You stand looking at the child, who continues to scream. After a short time, another similar looking child walks up to the first, stops and then joins in the screaming.
You start to wonder what they might be screaming about, just as a third child joins them and also starts to scream. Then a fourth. Then a fifth.
Soon, a steady stream of children are gathering outside your window, screaming, screaming.
You begin to feel a bit bored. What should you do?
