I don't want your half-serving of pasta you made last week, I don't want your peach slices in a ziploc bag that you don't remember where you got, I don't want your leftover meat you found in the freezer, I don't want "Well I brought too much, do you want a little?" lunch at work. I don't want something you bought and didn't want because the package was damaged. I don't want things you buy, rummage around in, and decide you don't like. I don't want the ingredients because I asked about the recipe, especially when it makes far more than I could use. I know people are trying to be friendly and all, but my god, stop it.
