When I was a kid right through to my teen years I was allowed to go about as long as I was with my older sister or friends, never alone. When I was very small we lived in a tiny town where the parents looked out for each other's kids. We went to the park by ourselves when we were 5 (me) and 7 (my sis). By the time we moved to a busier area we were quite independent and roamed about the whole town by ourselves, went to the mall, the local parks and ponds, stores. We were 7 and 9 when we moved to the larger town. This was in 1990 and there was a kidnapper prowling around. However, we were taught not to ever talk to or get in cars with strangers, and we were forbidden to go out alone. We walked to school, and were at home by ourselves after school too.
When I was 12 I had to walk 45 minutes to the public transit bus at 6:30 in the morning and ride another 45 minutes, then walk another half hour to get to school. By the time I was a teen I was taking the skytrain downtown alone and waiting for the bus late at night. I had no curfew, and pretty much went wherever I wanted.
I had more freedom growing up and as a teen than most other kids my age. I'm not sure if my mom gave us too much, but I have to say we knew the dangers as well as any adult, and were always out in groups. A handful of times I was alone when I should not have been in bad areas, and I was fully aware of how foolish I was being. My mom knew where we were at all times because we felt we didn't have to keep any secrets from her. If we drank, we could call her up and count on a ride home and know we wouldn't get in trouble for it.
This is just my own personal experience. I do know that a lot of my friends had far less freedom than I did and got into a lot more trouble. Apart from a stupidity blip when I was 16 and 17, I was actually a very responsible, mature kid who knew right from wrong.
That being said, I am unsure of how much freedom to give my
own kids when I have them, because I do not trust anybody! Kids today act like adults, 8 year old wearing briitany spears outfits. When I was 8 I wore matching sweat pants outfits with sparkly kittens on them!
Kids today are exposed to a lot more sexuality via the internet and TV, and even from when I was a kid the world feels a lot more dangerous. I would not walk alone at night, so I would be hard pressed to let my kids be out and about at night.
