Cách sử dụng
The expression "once bitten, twice shy" means that if someone has had a bad experience with something, they will be cautious and try to avoid getting into the same situation again. For example, if someone invested money in a stock and lost a lot of money, they might not want to invest again because they are afraid of losing more money. If someone has been hurt by something or someone before, they might be more cautious in future situations to avoid getting hurt again. This expression is often used to remind people to be careful and learn from their past experiences.
