I ironically got called childish for liking cartoons by an anime fan. It annoys me when people are ignorant to the obvious hypocrisy, as not all cartoons are 'funny' or 'kid-friendly'. And it's not just anime, it's all types of cartoons from all countries.
In fact, I've watched SAW and yet watching animated movies like "Watership Down" and "Plague Dogs" still freak me out because of their violence. Strange.
I actually am interested in becoming a cartoonist myself, which I am cautious when announcing it, since not everybody in the artistic community appreciates cartoons. I'm a self-taught artist, but I hope to take classes this summer and am thinking about going to the Art Institute of Philadelphia, which has a great animation course.
On the maturity level, I can say I'm a bit both immature and mature. I'm immature because I sometimes just feel so nostalgic and sometimes still feel the need to get comfort from my mom when I get scared. XD;; But otherwise, I'm a lot more mature than most people my age... I mean, I'm 16 and can relate better with adults. I'm pretty open and welcoming of other people's opinions and am not afraid to admit I'm wrong, which is unfortunately something that I found lacking in a college kid who disliked me. (Same guy who thinks I'm immature for liking cartoons, as mentioned above.)
