I Broke My Kid's New Toy

Yesterday was a good day. I got to spend it making cookies and teaching my six-year-old how to read a map. We had fun, and it felt like we were growing closer. But then came the inevitable part - clean-up time. His new puzzle set somehow ended up on the floor near his bike. As he was leaving to go play outside with friends, I didn't think twice before picking it up to put it away. One minute later, my heart stopped when I heard a loud crash and saw pieces of the puzzle scattered across the kitchen floor. My hand slipped, dropping the box on its corner, shattering every piece into tiny bits. It was so sudden and unexpected. Why did I have to be clumsy? He loved that toy so much; it wasn't even an accident. I felt a mix of guilt and worry - what am I going to say when he comes home?
