If someone is willing to rise early in the morning and pack warm food into a hand-washed, preheated thermos, it would be bad form to leave that food in the thermos untouched. Three days in a row.
Do not, under any circumstances, refer to that food as "disgusting."
That's it! Bread and water* for the rest of the week!
*Note to Texas DFPS: Bread will include meat, fish, or legume protein. There will also be some kind of fruit. And maybe a cookie.
