有一首歌叫Calendar Girl 谁知道这个日历女孩是什么意思啊？知道的请指点一下，谢谢了！

If I am lost for a day; try and find me 如果我迷失了一天，试着去找我
But if I don't come back, then I won't look behind me但如果我没回来，我就不会回头了
All of the things that I thought were so easy我曾想这一切很容易
Just got harder and harder each day但现在变得越来越难
December is the darkest and 十二月最黑暗
June is the light but this empty bedroom won't make anything right六月最光明，但空荡荡的卧室使做什么都觉得不妥
While out on the landing a friend I forgot to send home去接朋友时，我忘记回家的路
Who waits up for me all through the night谁等了我一整夜
Calendar girl whos in love with the world 和世界相爱的日历女孩
Stay alive仍活着
Calendar Girl whos in love with the world 和世界相爱的日历女孩
Stay alive仍活着
I dreamed I was dying; as I so often do像我平常一样，我梦见我要死，
And when I awoke I was sure it was true当我醒来时，我确信那是真的
I ran to the window; threw my head to the sky我走到窗边，探头向天空望
And said whoever is up there,please don't let me die说着无论谁在那里，请不要让我死
But I can't live forever,I can't always breath但我不能永远活着，我不能永远呼吸
One day I'll be sand on a beach by a sea某天我会变成海边沙滩上的沙
The pages keep turning, I'll mark off each day with a cross生活一直过，我会用十字来记录我的每一天
And I'll laugh about all that we've lost我会笑对我们失去的东西
Calendar Girl who is lost to the world和世界相爱的日历女孩
Stay Alive仍活着
Calendar Girl who is lost to the world和世界相爱的日历女孩
Stay Alive仍活着
