Nothing, this was elementary school. Our teacher would tell little Carlos to put his pants and underwear back on and everyone would be on the floor laughing their ass off. I know nowadays in our politically obsessed world I don't think a teacher would want to get it out there that he allowed a 7 yr old to be running around nekkid in his classroom under his supervision
, this sounds a lot worse than it was. Back when I was growing up, this wouldn't be an issue. Pretty sure we did a lot of highly questionable things that wouldn't be acceptable by today's standard.
We only did it between friends of ours or someone who had a great sense of humor for a good laugh. Like I said, I've also been the recipient of it, it's funny as hell and we were immature. It was never meant to be in a mean spirited way and if someone was really upset about it we would just stop. Everyone in our classroom always had a laugh over it.
