I found a way to resolve my diet predicament. Because it has been rather expensive for me to buy lunch at the cafeteria, I am replacing the unhealthy sandwiches with store-bought baby spinach. It is A LOT cheaper. In order to make sure that the rest of my family did not get to my spinach, I put masking tape on the container and wrote on it, "You eat this, I shoot you." I know that this sounds rather selfish, but otherwise my mother will very likely try to use my spinach for other purposes. MY spinach!
Now that I have greens at my disposal, I can get in my much-needed nutrition during lunch. Perhaps this strange diet will actually work.
