It Takes Two to Tango(when two people work as a team. they are both responsible for the team's successes and failures)
Look how crooked the linoleum is along the edges of the wall. It looks just awful!
I never said I was an expert in laying linoleum. Besides, it takes two to tango.
Just what do you mean by that?
Well, you're the one who gave me the measurements. If the job turned out badly it was just as much your fault as it was mine.
Maybe so, but if you'll remember, I wanted to hire a professional to do the job. You were the one who thought we should save money by doing it ourselves.
I guess we both learned a lesson. Next time we'll know better.
crooked = 曲がった、ゆがんだ
