One of the very few things that made my mom angry was wasting or damaging things through carelessness. Once I brought a snake into the house, it got loose, and we never caught it. My mom, who was afraid of snakes, just asked me to promise not to do that again. But she would have been angry if I dropped a bowl of food. (Well, maybe she wouldn't have been when I was a toddler. I can't remember that far back.)
