My teenage son does this every night. Bought a ton of containers even and announced he was cooking for himself. Rarely succeeds and ends up eating what I made. It's a regressive effort to show he doesn't need you and is independent. Don't waste your IC time on that. It's just teenage posturing. Ignore and eat out in the garden so you can enjoy your food.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
