I like drawing on bread
That's kind of unique. Why would you draw on your bread?
I just like doing silly things with my food.
It's fun to find different ways to have fun, but I think there's better ways to have fun and doesn't involve the potential waste of food.
So it's okay to draw on things that belong to someone like your clothes and books but not okay to draw on bread?
No, I'm not saying that. My main point is that we all should do our best not to waste food. I think understanding people that are not as well-off would love to have that food and not see it go to waste.
