I don't remember but this is all right before a big move/him graduating and everything. I'm pissed at the situation, at him, and everything (damn period).
Streptococcus bacteria naturally live in your mouth. It's when they get out of control that you get sick/cavities/ect. I figured this all out by the Giant Microbes. ^^
I had no idea that a cavity was an actual disease/germ/whatever. I thought it was just a hole in your teeth from too much sugar erosion. Unless that "cavity" germ is from sugar or something.
