Little bones little coloured stones
Try to keep try to keep you warm
If you wanna know wanna know your mind
Leave it all leave it all behind
There are things that are better left alone
So many questions out of your control
I don't wanna know how this is gonna end
Coz it won't stop the rain from coming down again
And I don't need that superstition fortune telling future magical
I live a life unpredictable
I live a life unpredictable
Little leaves little leaves will form
Try to see try to see the storm
If you wanna know wanna know your heart
Lose it all lose it from the start
There are things that are better left alone
So many questions out of your control
I don't wanna know how this is gonna end
Coz it won't stop the rain from coming down again
And I don't need that superstition fortune telling future magical
I live a life unpredictable
I live a life unpredictable
Unpredictable
Unpredictable
Unpredictable
Unpredictable
I don't wanna know how this is gonna end
Coz it won't stop the rain from coming down again
I don't wanna know how this is gonna end
Coz it won't stop the rain from coming down again
And I don't need that superstition fortune telling future magical
I live a life unpredictable
I live a life unpredictable

北京午后的细雨，云南悠悠的日光，东京透蓝的天空，还有丹麦清冽的晚风，都投射在你低垂的眉眼中，你浅笑的嘴角上。千千个日夜翩跹，万万个春秋悄然，时间的脚印越拉越长，皎洁月光，心口朱砂，故梦前尘，日月山河，都是你年少的模样。 面露羞涩笑容的干净少年转眼间蜕变成了男子汉的模样，想把世界最浪漫的都给你。在你最美好的年华里陪你一起长大 17岁生日快乐
