Yes, Teenagers Unite!
Well...I'm ashamed to say I was once one of those kids in your local club that doesn't paint his own models, doesn't know the rules, and didn't like to lose very much
When I first started out in this hobby I was 11 and picked up Space Wolves because I liked dogs...My older friend played IG and I liked how 1 of my squads could tear one of his apart...I got the codex and after I got done reading that I thought Leman Russ was the Emporer and the space wolves were renegade marines
but now 5 years later I'm 16, I can drive, and I much smarter. I put down my old SW host, Turned them into Iron Hands, and started a Kroot Mercenary force....and despite how I was when I was little I earned most of the respect I losted back then back...
Oh and now I'm a fluff maniac!!! Only reading one codex confuses you aalot
Moral of the Story: Don't be mean to the inmature brat that picks up the hobby be patient and show them the light, they may just be respectable gamers some day
