At first I was not quite willing to sit down and watched the 90-minute football match. Usually I just checked the results because I thought that was dull to watch a game in which players kicked a ball each other. Therefore, my father loves football. During the World Cup in 2002, my dad stays up late just to watch his favorite sport. Seeing his strong interest in this game of 22 men run after a ball, I decided to sit down to watch the game. I found the game excited, and my dad explained for the rules. We shared our joy. Football is not too badly as long as I watch it with my dad!
