I have close to 10,000 posts, you're just not looking hard enough; or we're not on at the same time and you're typically banned before I even know you were back.
But in reply. He's not legally an adult, he's by my count (14+3) so, he's still technically a child anyway. Video games aren't always directed at children, many are because that's the key sector of the gaming market. You look down on Cez because he has no social life, you then say YOU have no social life and state that he thinks that it's cool to have no social life and to be an arrogant prick.
A quote from the first post:
"my priorities will undoubtedly be based around studying and socialising rather than posting amusingly-captioned pictures of cats and correcting the spelling of people I?ll never meet."
So now he's leaving in part to develop his social life. I don't see the problem? Sure, he's an arrogant jerk a lot of the time, but that's just who he is. That's probably your only valid point, everything else you say, you continue to contradict yourself by being the same as him in those respects.
