it takes two (to do something)
Two parties are responsible for a certain action or situation in which they are involved. Your son is blaming mine for what happened, but it generally takes two to get into a fight. We're all ready for the merger, but it takes two to make a deal this big work, and the other company has been dragging its heels on the paperwork.
