That sure was a lousy day.
But I'll go you one better(actually worse).
This also happened at a birthday party,when I was 10.I had to go to the party with my 9 year old girl cousin.During some game we were playing I pulled up my cousin's dress,exposing her panties.She screamed and ran inside crying.Her mom saw what I'd done,grabbed me by the arm and followed.We ended up in a bathroom with me being made to apologize and explain.My excuse that it was just a joke didn't sit well with my aunt.She said that showing me how it felt to be embarrassed would be a fitting punishment.I was worried that she was going to parade me out infront of everyone in my underwear,when she told me to take off my clothes.My aunt's idea was even worse.She had my cousin change into my shirt,shorts,socks and shoes.Then she put my cousin's socks and shoes,and frilly dress on me!She even made me wear her hairbow in my hair!
The kids and their moms laughed at me and teased me.I was made to stay like that for the rest of the party.
Now THAT was a LOUSY and HUMILIATING day!
you were freaking 5 years old get over it!!!
your introduction to the world of sissyhood!
