We all get through somehow

If you think that loves is for good
I tell you I'm the one who misunderstood
If you think that love is for real
You're gonna need a heart of steel
You're gonna need a heart of steel

We all make mistakes
We should have what it takes
To get through all the heartaches

It's the natural thing that should be understood

You're gonna need a heart of steel
You're gonna need a heart of steel
That's for real, that's for real, yeah

Since you've been gone [bad word]  I just couldn't carry on
Since your goodbye
I thought I would just lay down and die

You better dry your eyes
You should've realized
But who am I to criticize?

It's the natural thing that should be understood
It's the natural thing that should be understood, yeah

If you think that loves is for good
I tell you I'm the one who misunderstood
If you think that love is for real
You're gonna need a heart of steel
You're gonna need one heart of steel
