When I turned 18 I realized there wasn't much of any difference between being 17 or 18. Everyone still saw me as a kiddo T . T even as a 22 yr old 25+ yr olds still see me as a kiddo.
But vice versa, after I was an adult I realized that most adults are just kids themselves.
Don't let your age hold u back from doing the thing u want. If there are things you still want to do when ur 17 and someone tells u no cuz ur 18 then like tell them to shut up lmao
Oh for reals though, enjoy any teen spaces ur public library can offer. Mine offers 3d printing and a studio booth for teens I can't use that anymore cuz I'm over 18 lol
