Ta biết anh buồn khi ta rong chơi , khi ta phá cách . Ta tự nhận mình là một cơn gió hoang ".. mà gió thì vô tình ..." .

Ngày quốc khánh là ngày lễ quan trọng của một quốc gia. Nó đánh dấu một sự kiện lịch sử, chính trị hoặc văn hóa gắn liền với lịch sử Nhà nước hiện tại của quốc gia đó. Tại hầu hết các nước, ngày quốc khánh đánh dấu sự khai sinh của quốc gia: ngày giành được độc lập như ở Mỹ, lật đổ chế độ cũ như tại Pháp, ngày thông qua hiến pháp như ở Thổ Nhĩ Kỳ...
