Is this true?

If this is a dumb question, please forgive me, I am an amateur. My friend,
who drinks wine all the time, says once you open a bottle of wine you have
to drink it immediately or it will go flat and lose it's flavor. I've had
opened bottles of wine for weeks and can't taste the difference. Is what
she is saying true?
