The power of two

Two to Tango: When the time comes, I hope we'll be able to meet. It takes two to tango. I am ready, the arena is ready

Two hands to greet: There is no friend like an old friend who has shared our morning days, no greeting like his welcome, no homage like his praise.

Two for Love: In the arithmetic of love, one plus one equals everything, and two minus one equals nothing. Two wings to fly: You cannot prevent the birds of sorrow from flying over your head, but you can prevent them from building nests in your hair.
