Cause I .......

The book that i gave,
The things that I've done,
The attention that i gave,

It's all have a reason,
It's all because of something,
I do because of something,

I can't tell you what,
I can't tell you why,
I just can do,

I hope you understand the reason,
I hope you can read the answer,
I hope you know the cause,

I will tell you why,
When that time has come.
