Il faut savoir [English translation]

One must know

How to keep smiling

When the best has been taken away

And all that is left is the worst

In stupid life that you want to cry

One must know

No matter what

How to Guard his dignity

And no matter how much it costs

Leave without looking back

Face the fate

That disarms us

And in front of the lost happiness

One must know

How to hide the tears

But for me, my heart

I Didn't know how

One must know

To leave the table

When love I'd no longer served

Without attaching yourself, in a pitiful air

But leave without making a noise

One must know

How to hide the pain

Under an everyday mask

And hold back the cries of hate

Which are

The last words of love

One must know

How to remain like ice

And hush the heart

That is already dying

One most know

How keep up appearances

But me, I love you too much

But me, I can not

It is necessary..

But me, I do not know how
