grow up ? happy ?

have you ever think like this :" the more you grow the more you hurt someone's feelings "?

when you was child even you're act annoyed , people arround you can accept it and you just get chance to fix it . 
Now when we are grow up , just once you acting annoying , people immediately make a space with you :( .
that's why i hate being old :( , if there's really neverland i wanna live at there bring all of things who can make me happy.
when you grow up You will rarely smile , You always think to look nice (and this is makes us fake ) , You always think
to look mature .
For me become mature is not easy and  need a long long time for adaption it :(
