Il faut savoir [English translation]

One must know

To still smile

When the best has pulled back

And all that is left is the worst

Of a stupid life that you want to cry

One must know

Cost what it may

Guard your dignity

And no matter what it costs

Go away without looking back

Face the fate

That disarms us

And to happiness lost

One must know

To hide the tears

But for me, my heart

Didn't know how

One must know

To leave the table

When love has come and gone

Without attaching yourself, a pitiful air

But leave without making a noise

One must know

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

To remain like ice (cold)

And hush about a heart

That is dying

One most know

It is necessary to 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
