End of understanding de Willie Nelson

Each time you hurt me, you say you're sorry.
i try to understand, and say: ";
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:

and there must be an end to understanding,
