Since you don't want to go, go. What about the future interview? Then be fully prepared. No one will laugh at you. People always care about themselves the most, just like you remember when you were in junior high school and your pants were not zipped up? Get used to it and participate more in the future. The big deal is being laughed at. No, in fact, others won't laugh at you. Just be fully prepared. If you forget the words, improvise and talk nonsense.
