My character curses because it's basically me. I'm an angry black guy and I tend to curse. A lot. In an apocalypse, I can see my and other's cursing habits increase because all morals and shit go out the window and no one cares how other people think/feel about their vocabulary.

Four days is pretty good. Hopefully everyone'll meet up and have happy fun times. Also that soldier guy, Elbert, is a dick.
