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 her 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!
