I remember when I was thirteen the stance on how old you were determined how cool you were. Being between twelve and fourteen made me fat and immature. While twelve year olds were shunned and unwelcome. Fourteens were privileged to be hitting puberty (which I didn't hit till fifteen) and some how just a little cooler than their subordinates.
Though now I just think anyone on NGs is cool whether their six or sixty, which would be pretty fun because they'd either be trolls or badgered to leave, now I know better.
