I should start by saying I went to Catholic school and had to change for gym(later transfered to public, no uniforms) Well one day while changing we got out a gym a bit late so we were being rushed to change. I stuffed my sneakers in my bag and left and walked all the way up to the classroom without realizing that I had not put my dress shoes back on. I didn't even realize until the end of the day(It was 3rd grade we didn't switch classes) when I got up to get my coat to leave.
I felt really stupid but nobody said anything and there was a LOT on my mind. I just had a big in family death and the day after that my dog died(they got him before me so losing him was traumatic.)
Also one time when they were taking class photos I got REALLY bored(it was taking unusually long) so I found a paper clip and just started messing with it. I ended up dropping it against the wall and it fell behind an electric outlet and the thing sparked made a loud noise and a big black cloud came out of it. The teacher asked me about it but I claimed I had no idea.
