Real citation: "Yesterday I found myself in a store that is not my favorite. But, I am a captive to the low prices and wide selection. What can I do? While shopping at said store, I split away from Garry and the kids to go find another tupperware-thingy-majigger. We're big on organizing right now. I was wearing black pants, a black shirt, and a green sweater. My hair was a hopeless mess. Make-up? Not sure if I really had any on. It wasn't my best day."
