The date

A schoolchild (8-9 years old) as a homework must learn the dates of the invasion of the areas of his homeland. Throughout the day, he tries to remember history, but seem he cannot come to terms with this dates. He then falls asleep playing with military toys. He dreamed of war; the sky is full of planes for military missions. Cannon fire turns into fireworks in the sky.
Waking up, the boy looks with interest and pride in his book, as there the dates that he tried to remember were crossed out.
