Why is it you?

The two old men had ugly looks on their faces, but neither of them said a thing.

The looks in their eyes made it clear that they had their guards raised just in case anything happened.

If anyone were to do anything to them, they would be ready for it.

The problem was…nothing happened.

So all they could do was stand there with their guards up while they were still injured. They didn't even have time to stabilize their injuries since they were on guard against anything that would come their way.

After a long time, the first old man said, "What? Are you too scared now?"

The second old man followed up by saying, "Right! You ambush us and then run?"

"Who said that I'm scared of you?" 

The two old men tried to find the source of this voice, but once again they couldn't find it.
