Stairway to heaven

Something my mum sent me in an email:

有一对兄弟，他们的家住在80层楼上。有一天他们外出旅行回家，发现大楼停电了！虽然他们背着大包的行李，但看来没有什么别的选择，于是哥哥对弟弟说，我们就爬楼梯上去！于是，他们背着两大包行李开始爬楼梯。爬到20楼的时候他们开始累了，哥哥说“包包太重了，不如这样吧，我们把包包放在这里，等来电后坐电梯来拿。”于是，他们把行李放在了20楼，轻松多了，继续向上爬。
　　
　　他们有说有笑地往上爬，但是好景不长，到了40楼，两人实在累了。想到还只爬了一半，两人开始互相埋怨，指责对方不注意大楼的停电公告，才会落得如此下场。他们边吵边爬，就这样一路爬到了60楼。到了60楼，他们累得连吵架的力气也没有了。弟弟对哥哥说，“我们不要吵了，爬完它吧。”于是他们默默地继续爬楼，终于80楼到了！兴奋地来到家门口兄弟俩才发现他们的钥匙留在了20楼的包包里了。
　　
　　有人说，这个故事其实就是反映了我们的人生：20岁之前，我们活在家人、老师的期望之下，背负着很多的压力、包袱，自己也不够成熟、能力不足，因此步履难免不稳。20岁之后，离开了众人的压力，卸下了包袱，开始全力以赴地追求自己的梦想，就这样愉快地过了20年。可是到了40岁，发现青春已逝，不免产生许多的遗憾和追悔，于是开始遗憾这个、惋惜那个、抱怨这个、嫉恨那个，就这样在抱怨中度过了20年。到了60岁，发现人生已所剩不多，于是告诉自己不要在抱怨了，就珍惜剩下的日子吧！于是默默地走完了自己的余年。到了生命的尽头，才想起自己好象有什么事情没有完成，原来，我们所有的梦想都留在了20岁的青春岁月。

I'll translate it, but it doesn't have the same feel as the chinese lol.

Basically 2 brothers live on the 80th storey of an apartment building. One day they return home from a long vacation, and they didn't realise that the building's electricity had blown so the elevators weren't working. So, they decided to climb the stairs. Carrying all their luggage, they slowly made their way up to the 20th floor. At this point, they were both soooo tired from climbing all those stairs... the older brother said, "how about this, we leave our luggage here and come back to get it when the electricity's back up." So that's what they did, and they kept climbing.

They laughed and chatted with each other as the climbed, until they reached the 40th storey. At this point, they were really starting to get puffed out and were despaired to think that they were still only halfway there. They started to argue with each other, each blaming the other for not paying attention to the electricity announcements. By the time they got to the 60th storey however, they were both too tired to even fight. The younger brother said, "Let's not fight, just focus on getting up these stairs." So they peacefully and slowly climbed up the last 20 flights of stairs and finally ended up at the 80th storey. When they got there, they realised that they had left their key in their luggage, back on the 20th floor.

Some people say that this story is actually a reflection of our lives: Before the age of twenty, we live under the expectations our families and teachers, burdened with a lot of pressure, and we are not mature enough, or skilled enough, so we can't live without them. After passing the age of twenty, we have left this pressure, left our burdens, and begun to use our own abilities to chase after our dreams. But when we reach 40, we realise that we have passed our youth, which leads to much regret, and we begin to regret this, and regret that, complaining about this, hating that... so we spend the next 20 years complaining. When we reach 60, we realise that there is not much life left, so we tell ourselves not to complain and to cherish the rest of the day :) So, we quietly spend the next 20 years in peace. At the end of our lifes, when we look back and remember if there is anything that we never completed, we realise that all our original dreams and aspirations were left at the age of 20...
