Two distinguished older gentlemen stand outside a house, trees in background, both with white hair, the taller man having his arm about the other man's shoulder as they face the camera from behind their corrective lenses.
The older men are colleagues.
The men are facing the camera and that does not necessarily mean that they are colleagues.
Just because one man has his hand on the other man's shoulder doesn't mean they are colleagues.
Not all men that are together are colleagues.
