    Last night my best friend left me her house keys and I used them for a neferious purpose. I stole her toilet paper. And than  I realized nefarious needs to be the word of the week. I love how the word nefarious rolls off your tongue, the pictures that it presents. Nefarious. A word I need to use more of.
