My parents always like to tell my embarrassing stories to outsiders. What kind of psychology is it? This will only make people think that I am stupid. Is it interesting?

Your parents always like to tell all your anecdotes to outsiders, but they think you will be interesting and. They don't think you're stupid, they just think you're stupid sometimes. It is also interesting to listen to it as a joke when you are bored. You don't have to take it to heart, others just laugh it off and won't take it to heart.
