(It) takes two to tango

(It) takes two to tango: Há coisas que só podem acontecer se houver duas pessoas envolvidas

 “Alan: You're always arguing! Stop arguing all the time.

Jane: I can't argue all by myself. It takes two to tango.”

“ Fred: Did you hear? Janice got herself pregnant.

 Jill: Well, she didn't do it all by herself. Takes two to tango, you know.”
