A girl at Italki, the other day, posted a message on her blackboard "I will never trust men again". That girl must have had some bad experience with men. This reminded me of the subject provert "One bitten, twice shy". It means that someone who has been hurt or who has had something go wrong will be far more careful next time. In Chinese there is a similar saying 一朝被蛇咬,十年怕井绳. Shy here means "frightened". Do you have some personal experience which this proverb applies? Please write about it.
