I would say I am pretty mature when I need to be. Sometimes, I believe that being super mature is quite boring. I tried that once, so I should know.
I believe I am pretty mature. And I agree with @MonsieurHappy that being mature all the time may be quite boring.
To me, I feel like I am more mature than what is normal for my age. Maybe because I've gone through a lot of stuff that has made me realize and learn how to think before I act. One thing that relates to this is my social anxiety, which has actually helped me because it prevents me from making some stupid decision or whatnot. But yeah, due to a lot of stuff I've went through (partially thanks to here) I've understood that even at my age I can still be smart about what I do. Think for the future when you make decisions guys, and think before you act.
In my opinion, I would say that someone who was mature wouldn't really go around professing how mature they are. Actions speak louder than words, especially in that case.
To be honest, it really depends for me. I can be really mature when it's necessary, but at the same time I can be as immature as @Left4Lag ;>
Honestly, i think im pretty mature for my age (13). I have had a lot of trauma in the last few years, which has taught me how to cope with it better. I also hang out with a lot of old people, I have very few friends that are my age.
I don't scream in game or go around spamming the chat. xD Those people who do that are pretty annoying. xD
I rate it okay. But in fr /fr I say my life in chat, so if you don't respect that, then /friend remove Tacosinmytummy.
