Embarassing builders bum!

I was in year 6, my first year in my new school. I was sat at the front of the hall with all of the girls and all the boys were sat at the back. I think we were rehearsing for a christmas play or something. Anyway, us and the boys were sat on the floor while a few of the other kids were on the stage practising. Then I heard the boys behind me laughing at something, and when i turned around, they all started shouting builders bum, builders bum! I just turned around and went bright red and I was so embarrassed I was frozen and didn't even pull my trousers up! So they got such a long look! One of the girls tried to put a jacked behind me and turn me around but it was too late. Do you think the boys will ever forget it? I am so embarrassed I cringe everytime I think about it. I have done many very embarrassing things in my life, but this just puts the icing on the cake!

Hey Sophia, i just have a question- how did your pants end up down??
