One of my happiest memories as a child is going by the river and sitting lazily on the bank.There I would watch the water downstream. There I would also watch the bamboo trees under pressure from the wind and watch them elegantly to their original position after the wind had . When I think about the bamboo tree’s to bounce back(弹回) to its original position, the word flexibility(柔韧) to mind. When used in relation to a person, this word means the ability to from shock, depression or any other situation that extends the limits of a person. Have you ever felt like you are at your point? , you have survived the experience to live to talk about it, though during the experience, you felt emotionally(情感上的) tired, mentally exhausted and you even felt physically. Life is a of good times and bad times. The next time you are experiencing one of those bad times that take you to your breaking point, bend but don’t break. Try your best not to let the situation get the best of you.
