puberty? bro that doesn't mean you're gonna be grown up lol puberty has a whole reputation for "turning you into an adult" when really it just means your body is changing so that if you choose to have kids someday, you can. For some kids, puberty has just been coming early for them. Sometimes 8 yr olds begin puberty! It doesn't mean you're "growing up" all of the sudden, it means our bodies are genetically programmed to start developing then. And it happens over a long period, it's not like you're gonna wake up tomorrow and be six feet tall. If you're starting now, you have AT LEAST another 5 years.
