Have you recently looked back at pictures of yourself from high school or your freshman year of college? Here is how your experience will probably go: your eyes will widen a little as you slowly start to shake your head... then you'll bow your head, close your eyes, and laugh...
[note: this only really works if you have been out of high school for more than four or five years... if not, then your pictures on Facebook are probably still socially acceptable.]
If you haven't done this, you should. I'll bet you ten bucks you'll get a really good laugh out of it.
