Yes, you did. Thank you. By law, I have to watch a "Bloodborne Pathogens" video at the start of every school year, to know how to deal with things if a kid cuts himself with scissors or whatever in my room. The video, and school policy, state that I have to stop the bleeding and clean up the area in a certain special way with a certain special kit (with latex gloves and all that), and then get a custodian to use some special cleanser on the area, and basically turn it into a little HazMat scene.
I have always found it to be pretty over the top, but the upshot is, the video and policy together have done a fine job of making it sound like someone could get HIV by just looking cross-eyed at a puddle of blood. I know it's not that easy, but the drama of the whole thing means that I have no idea exactly how hard or easy it actually is to get infected (aside from, as you mentioned, things like cutting my body all over and rolling around in infected blood). So I figured I'd ask.

Thanks for clarifying.
