I dreaded it, considered just throwing away perfectly good tupperware, but was ultimately able to psych myself up enough to open it up and wash it. How? I was all, "What's the grossest thing I've seen at work? Maybe oozy stasis ulcers with maggots crawling in and out? Well, this isn't maggot infested stasis ulcers gross, so it'll be okay." And thus, the tupperware was recovered. Thanks, nursing.
