Kids these days.

Elementary teachers these days are dealing with a new problem. My mom's school recently had to address the issue of "doing their ABCs". Apparently, kids take an eraser and rub it back and forth on their skin until they "burn" it, and then a welt forms. They call this "doing my ABCs". After a few days, the welt goes away and usually a scar forms. My mom has a couple of 4th graders in her class with these scars on their arms and hands.

What's up with these kids? I don't get the penchant for self-mutilation. The most dangerous thing a kid ever did when I was in elementary was to shave his eyebrows off. They of course grew back. Are kids getting dumber?
