I was born in the mid 70's and was raised in the 80's as a total latchkey kid in the suburbs until I was around 11, then we moved to a rural area outside of town where my closest neighbor was about 1/4 mile away where I continued a virtually entirely unsupervised life in the country. When I was in the suburbs, I spent my summers at the houses of friends within about a 4-block radius. Lots of bike riding, going down to the corner market to buy pop/candy, days at the lake, and camping. I spent a lot of time in front of the TV too, watching MTV & HBO. In the country, I had a super nice treehouse. It had a deck, screened windows, and power would be run out there via a stupidly long extension cord, which allowed me to have a small color TV, a huge fan, my NES, and a stereo system. I also had my comic long boxes that I hauled up there every summer and a big cooler where I kept food. I lived out there every summer for months at a time up until I was 16 years old! I had a moped gifted to me when I was 13 and I spent the summers solo exploring all the dirtroads and trails within a 10 mile radius of my home.
My kids today don't really have a reason to leave the house. They're connected with their friends 24/7 via technology. I also think it is why many kids today have no desire to learn how to drive. Where are they going to drive, school? That's not fun. Back when I was a teen, driving was the escape from home that we all desired so much. My kids even watch movies virtually with friends. They both have amazing bedrooms and tons of hobbies too. They ride bikes occasionally and have been swimming at the lake entirely on their own for years (they just rarely go). If I was a kid, I would be just like them. They keep super busy with school activities and such though, so whenever they have downtime, they can do whatever they want. As long as they maintain good grades, participate in school activities, and do their chores, my kids have always had free reign to do whatever they want. They want to chill online with their friends, chat, play games, and watch movies. It is all the same things I used to do with my friends, only now you can do all that from the comfort of your own home.
