A 16 year old would be pissed if their little sister put on their prom dress and ripped it up and stained it. It's not a difficult concept to grasp and these aren't little kids. These are almost fully grown people who will be 100% responsible for their actions in less than 2 years. 16 year olds absolutely do (and SHOULD) have developed enough brains to know better than to play dress up in someone's wedding dress. They know better than to snoop through someones room/closet. And certainly know better than to put on someone else clothes without their permission. Let alone something as important as a wedding dress. I wish people would stop acting like these kids are 8 instead of 16. BTW, had to go all the way back to 8 because even most 12 year olds know better than to snoop through someone's closet and wear their expensive clothing without permission.
