She said no more than that, waiting for his reaction.

The young woman was still looking at him, waiting for his reaction.

Up and down the hall kids hung around, waiting for his reaction.

He kept waiting for his own reaction, but there was none.

He paused and looked at me as if waiting for my reaction.

He waited for my reaction, but I had none to give.

He turned and walked away without waiting for her reaction.

At the end he just stopped talking and waited for her reaction.

She did not wait for his or anyone else's reaction.

He and the woman are both watching me, waiting for my reaction.
