what you do
Watch what you're doing!
Sie sind für das verantwortlich, was Sie tun.
You are responsible for your actions.
— Der letzte Kaiser (1987)
What you're doing is dangerous.
Sie haben getan, was Sie tun mussten.
You did what you had to do.
You know what you’re doing.
Denn egal, was Sie tun, ich verrate Ihnen nie das Passwort.
Because no matter what you do, I will never tell you the password.
— James Bond 007 - Casino Royale (2006)
Sie sind ja alt genug, um zu wissen, was Sie tun.
You’re old enough to know what you’re doing.
— Ali: Fear Eats the Soul (1974)
What you're doing bothers me.
I know exactly what you're doing.
