Furthermore, I will even   17  help and when my offers are refused, I am   18  willing to walk away. And all these changes came from a disaster on an island.
Sometimes a person’s independence is a   19  of pride, daring, stubbornness and luck. I used to be too   20  since I was little. I was once a traveler who never asked for   21 , choosing instead to struggle with maps and signs until I found my way.
Then one day on the island of Koh Phangan, in Thailand, everything   22 . I was swimming in the ocean with Sean, my fiancé, when he was   23  by a box jellyfish(箱型水母). He   24 within three minutes, 25 years old. Yet when onlookers and travelers asked if I wanted   25 , stubborn pride and force of habit   26  me accepting. But two young Israeli women stayed.   27  my protest(反对), they were with me even when the police tried to cover up the   28  of Sean’s death. It was listed as drunk drowning to avoid hurting the   29  industry. The Israeli women   30  have walked away.   31 , without even telling me, they   32  their schedule rather than leave me behind.
33  I didn’t realize it at that time, I would not have   34  the disaster without these great women. Actually, the person who needs help the most is usually the last person to ask for it. I have learned   35  is better than refusing because it not only helps you walk out of trouble, but also helps you know the real meaning of life.
