When I was little (about 5 or so) we were all comparing our packed lunches in the dining hall. Somebody asked me how many sandwiches I had and I said two, and stuck up my index and middle finger (in the UK this is rather rude). OPne of the older kids reported me to the dinner ladie for swearing, and I had to stand at the naughty wall all lunchtime.
I hadn't even heard of swearing at the time and was really upset because I had no idea what I'd done.
