Hey uh I don't go out so this can be hard to judge but on an online game I don't really play much anymore but used to, a lot of people on it tended to treat me like I was a full blown adult, like around 30-40 and such. Was kinda embarrassing, but I guess since the game contains a community of young pricks, fairly understandable. I'm also told I've always maintained the maturity of someone in their 20's but not wise enough to be 30 yet, on places like this. Go figure. I guess my years of solitude keeping me away from other kids gay ass opinions allowed mine to develop properly, as well as a pretty decent generalisation in...GENERAL KNOWLEDGE. Yay!
When I was 14, I walked into a shop and succeeded in buying Grand Theft Auto: San Andreas by convincing the employee behind the counter I was in fact 18.
At the moment, with my long hair, glasses and scruffy "paedophile neckbeard + technicians goatie combo" I probably rate about 25-28 or something. Go win!
