Have you ever been punched by your Mother in public?

I took my Mother to a Anime and Video game Convention once. We went into this area where game designers were trying out their new games on the public. There was this one where you can have up to 4 people holding a microphone looking device with a glowing light instead of the speaker. The object of the game was to try and get the other players to dip their controller leaving you the last one standing. The Designer lady said 'Go!' and I guess my Mother heard something else. I didn't even see it coming and she gave me bloody nose. 😂
