It takes two..

Whenever an opinion is needed..it takes two to offer the full spectrum.
Whenever one raises his hand to say something..it takes two fingers to do that.
Whatever beauty one wishes to see..it takes two eyes to view it from both sides.
Whenever battery energy is needed..it takes two to work.
Wherever might you be..it takes two lungs to breathe the air that surrounds you.
Whatever one has sinned..it takes two saints to wash him off.
Whenever appreciation is gained..it takes two palms to applaude.
