Lyrics:

Each time you hurt me, you say you're sorry.
I try to understand, and say: 'OK.'
But there must be an end to understanding,
And the end of mine can't be too far away.

I try to understand that you're 'only human'.
And 'we all make mistakes' every day.
But there must be an end to understanding,
And I know that I just can't go on this way.

Don't you know that love and understanding go together:
Ask too much of one and both will die.
And there must be an end to understanding,
And I know, someday, I'll reach the end of mine.

Don't you know that love and understanding go together:
Ask too much of one and both will die.
And there must be an end to understanding,
And I know, someday, I'll reach the end of mine.
