Grammar: German "Perfekt"

Now listen to some more sentences from the dialogue:

Eigentlich habe ich der Krankenschwester schon alles gesagt. Actually, I've already told the nurse everything.

Aber eigentlich habe ich nichts falsch gemacht. → But actually, I didn't do anything wrong.

Sie haben Glück gehabt. → You've been lucky.

Habe, habe, haben – all forms of "to have". As a general rule, you can remember that all sentences which are not about movement take a form of "to have".
