《I understand》的歌詞是：
I understand
But I don't care
I'm not the one
Who's gonna cry tonight
I understand
But I don't care
I'm not the one
Who's gonna cry anymore
Yeah yeah yeah yeah
Yeah yeah yeah yeah
I don't want to hear your lies
I don't want to see your tears
Just tell me what you want me to believe
And I will do
I don't want to hear your lies
But I don't want to hear your pain
So why don't you just walk away
And leave me alone tonight
I understand
But I don't care
I'm not the one
Who's gonna cry anymore
Yeah yeah yeah yeah
Yeah yeah yeah yeah
With every moment
Every time we fight
The walls start to crumble
Falling to pieces around me
Soon I don't know who I am anymore
With every promise you broke
Every time you lied to me
Your face become so distant and pale
Your love has turned into hate
Yeah yeah yeah yeah
Yeah yeah yeah yeah
But I don't want to hear your lies
I don't want to see your tears
Just tell me what you want me to believe
And I will do
If you tell me now we could have it all
If you say it's not too late to start again
I might just take a chance with you tonight
And let you believe
I understand
But I don't care
I'm not the one
Who's gonna cry anymore
Yeah yeah yeah yeah
Yeah yeah yeah yeah
I understand but I don't care
Now I know who's gonna cry tonight.
