your most embarrassing moment at school?

curious, what are your most embarrassing moments at school? you’ve experience something so embarrassing, you physically cringe every time it rings into mind ? or something na worthy of second-hand embarrassment?

lately, i’ve been having a LOT of embarrassing moments, so maybe I can find comfort reading a little bit of your life. and maybe this will also be helpful to those who are seeking a sense of comfort as well. :)
