There are tons of boxes with this packaging, and guess what? It never works. In fact, if it does work, you should be worried, because that's some cheap cardboard you're dealing with. That's the dollar store level of cardboard. The macaroni inside might even be cardboard. I wish they would just say "cut here with scissors" instead, so that we could give up the hope of even trying this maneuver.
If you're a conspiracy theorist, this is just one of the subtle ways that the government makes us all go a little crazier every day. We expel so much energy being mad at the food boxes that we don't have any energy to be mad when ICE loses thousands of immigrant kids. That's right. I went there. That actually happened in 2018. Doesn't that sound like something that should have happened in 1918 instead?
