Well, I am 30 and I had some freedom in my childhood growing up in a (European) city but mostly under some sort of "supervision", if only playing in our garden instead of at the park with the other kids. I never had this group and social thing in my play time, nor any of those big-adventure-like undertakings you described and never done any "mischief", so you could say I did not enjoy such a huge/healthy amount of freedom and I didn't take it for myself. I have never been a group person all my life, I am mostly alone, especially since I moved to another country and city and it is hard for me to relate to other people or feel comfortable in a crowd or really enjoy going to a pub or going out. I am suffering from (at times severe) depression and anxiety.
