I don't mind people bringing food if it doesn't suck.

Fortunately, most people around me know their limitations when it come to cooking. Mostly I just don't like winding up footing the bill for food when I don't have the money to, so I'll take a few brought sides whenever I can to ease the burden on my purse.
(Oh and for the record, the little packs of seasoned Idahoan instant mashed are actually really, really good. I was shocked. My step brother bought some when he had wisdom teeth out a year or two ago, and I've been hooked. But to be fair, I despise lumpy mashed potatoes and the instant make a perfectly smooth texture for the satiation of my OCD.)
