Again, father and son stared at each other, the same thought running through their minds.

For a moment the father and son stared at each other, oblivious to their surroundings.

Father and son stared at each other, sharing the same sobering thought.

For a long moment father and son had stared.

But then his son was staring at these proceedings as if he were utterly lost.

Once again, father and son stared at each other in silent bafflement.

My son stared at me as if I'd suddenly grown an extra head.

Father and son stared at each other in the quiet room.

My son stares across the room at the blank screen of his computer, but I know he is not seeing this.
