Childhood is a time of life that represents innocence and happiness.

Patriotic songs are a different case. The lyrics to patriotic songs are usually in favor of one’s country and may be in opposition of others. It appears often in competitions or wars, to show sincerity in support one’s country. For instance, patriotic songs commonly come up in movies set in the past, usually wars. Soldiers sing their national anthems with their hands on their heart, before war in promise to take over the opposition for their country, or after victory. In sports, anthems come up according to the winner’s nationality. It tends to single out people’s minds and provoke nationalism, becoming less tolerant of the others.
