My parents generally don't give me any set times to go to bed. I just go to bed when I think it's a good idea or when I feel tired.
Back when my router worked, I had free roam of the Internet no matter what time of day. Sometimes, I'd just sit up on the forums or Blockland until 3am on Friday nights. I see no reason why I'm not allowed to have a smartphone/computer. Last Christmas though, I kind of got my way.
My mom kept hounding me to make a "wish list" for Christmas. First item was a computer, second was a tablet, third was a smartphone, fourth was something else. They noticed and explained how I can't have Internet technology for such and such reasons. Instead of editing my list though, I just left it how it already was so it otherwise looked pretty bare. Got an Android tablet on Christmas morning ;)
