Your most embarrassing moment?

This was when I was just 8 years old but it still feels like it was yesterday. One day I was at a store with my mother and I got a sudden itch in my nose and I got the urge to poke at it to get rid of the itch. Little did I now that the kid I liked was right in front of me and saw the whole nose scratching action. He said he noticed and I was afraid to show up to school the next day.
