Im from England and honestly American teens look so much older than they are. Im not just talking about teens in movies being played by older actors/actresses, if you look on social media there are many influencers from America that are young but look like an adult. Americans probably dont see this but im sure others can agree. Most girls in England look their age or slightly younger or older, but in America, all the girls look like they have already been through puberty years ago when they are probably still going through it. i cant be the only one that thinks it. i probably didnt explain it well but someone must understand
