"Is there blood?!?"

My four-year-old now responds to any exclamation of pain from any member of the family with, "Is there blood?!?"

Now, I'm not sure if he actually wants to see some blood, if he's truly curious about the severity of the injury, or if he's just mimicking me. I guess I'll have to wait to see how he responds when we finally get a "yes" answer to the "Is there blood?" question.
