There’s a lot of kids and teens on Reddit. I’m glad I was a teen on the Internet in the walled garden of AOL, so all the dumb and hormone-driven things I said there are probably lost on a hard drive in a landfill somewhere.
I'm glad to be part of the pre-internet generation where the limit to our cringe is a fleeting feeling of embarrassment while hazily remembering it, rather than having it played back in high definition at some inopportune moment.
I think as adults we should be able to recognize that we all went through this and look at it with a little compassion and understanding instead of holding it up for ridicule. As you say, people will feel embarrassed about it enough in the future.
