A sentence that helped me a lot this week is „that’s not my beer“, the German idiom meaning, „I accept I’m not responsible for this.“ So I built myself a reminder, lest I forget the sentence.
Edit: I reprinted it to correct the text to “Ceci n'est ma bière”
@daniel following to M. Magritte: though it is not your beer, it still is a picture oft your beer? So we can't really tell, whether you have to deal with it?
