What did the narrator do to ensure that no blood was spilled on the floor when he killed the old man?

Well this somewhat makes no sense because we don't know where this comes from, or even if there is a text that is for this question. Also, for the record there are younger kids on here just trying to get help and the last thing they need to be seeing is this. Not to mention the first answer someone else gave. We shouldn't be talking about these kinds of questions on here, even if they really are for school. This isn't the sort of thing that should be talked about on a place with children younger than Junior High students.

Don't post something like this again please.
