I broke something and my mom can't know what and I forgot what. So I say: "I didn't break anything, mom." But my mom isn't buying it. She looks at me with piercing eyes and says: "What did you break, Bob?" I don't respond. She says, "I'll find out anyway." I look up and down again. She says, "The later I find out, the harsher the punishment." So I cave in and say, "I don't know." "What?" "I don't know what I broke." She presses her eyes shut with her fingers. With a silly, high-pitched voice that sometimes lightens her mood I say, "I dunno," but now she's pressing even harder.
What do I do?
