Even back in high school I was a strong believer in just being yourself. I never tried to put up a front... If I had a friend that was into something that I thought was a little strange I'd try to understand it...
Nowadays, my baseball career is over due to shoulder surgery... I'm getting ready to graduate college with a degree in Mechanical Engineering and I work for DuPont....... some would call me a nerd just based on that.
But for anyone that is having trouble with social cliques that is in high school.... Don't ever change yourself for any reason other than for yourself. If you're into DnD... then be the best damn DnD player you can be... haha
