“I have friends like that—very straightforward and responsible, good at what they do, good home life. But they get stressed, and they blow off steam by posting aggressive comments on the web. Their web personality is different from their real personality. They keep them separate. They just laugh and say it’s okay to write whatever you can’t say in the real world, no matter how critical or negative it is. That does seem to be one purpose of the Internet for a lot of people.”Kotaro nodded.“But I think my friends are wrong. Their posts will never disappear. They think they’re just putting opinions out there. They don’t use real names. They say what they think. They assume no one pays attention for more than a few moments. That’s a big mistake.”“Most of what goes on the net, stays on the net—somewhere.”“That’s not what I mean. No matter how carefully they choose their words, whatever they say, the words they use stay inside them. Everything is cumulative. Words don’t ‘disappear.’“Maybe they post a comment saying a certain actress should just die. They think they’ve blown off steam by criticizing someone no one likes anyway. But those words—’I hope she dies’—stay inside the writer, along with the feeling that it’s acceptable to write things like that. All that negativity accumulates, and someday the weight of it will change the writer.“That’s what words do. However they’re expressed, there’s no way people can separate their words from themselves. They can’t escape the influence of their own thoughts. They can divide their comments among different handles and successfully hide their identity, but they can’t hide from themselves. They know who they are. You can’t run from yourself.”Mom would say, “What goes around, comes around.”“So be careful, Kotaro. If the real world is stressing you out, deal with your stress in the real world, no matter how dumb you think it makes you look. Okay?”
