I often went to a park near my home. I always saw a little boy sell _________ there. He tried to ask everyone to buy his flowers. When he saw _________, he always said, "Sir, buy a flower, please!" _________ I never bought any flowers from him.

One day, I went to _________. The boy was there again. I didn't _________him and walked past him into the park. When I came out of the park, the boy was still there. But he didn't ask anyone to buy his flowers. I wanted to know _________. I walked up to the boy. He looked at me but didn't say _________. "Boy, why don't you ask people to buy your flowers today?" He _________, "Because my sister is dead(死的). I don't need much _________ now. You can take a flower for free." I bought all his flowers. But I felt so sorry, because I didn't give him any _________ when he needed me.
