What if I said I'm not going to finish my food on purpose?
Why are you not going to finish your food?
Because the food tastes awful.
If you don't want the food then you should offer it to someone else in the house. Wasting food is a bad habit.
Why would I do that? I'm not sharing this food with anyone.
But if you aren't going to eat it anyway, is there any harm in giving it to someone else so it doesn't go to waste?
