His nose started bleeding like crazy, and once he saw the blood he started really freaking out. We got him (kind of) cleaned up while one of the library ladies filled out an incident report and brought him some ice in a towel and a foam airplane. The security guy also came over to see if everything was okay. They asked me a couple of times if I wanted them to call the paramedics. I was, like, "He's FINE. Just a little (or a lot of) blood!" I called Scott and told him what happened just to make sure we didn't need to call the EMT, though.
Needless to say, his poor little nose is quite swollen up and is pretty black & blue. Here are a couple of pictures taken that night. Now the swelling has gone down quite a bit, but it still has a little yellowish, greenish tinge to it.
