When you get a paying job to afford the purchase and upkeep.
When I was growing up in the 1970s, I am so glad I was never tethered to a smartphone like the children of today are.
It's hard for children of today to imagine but when I went outside to "play", I would be gone for hours, sometimes the entire day, on my Huffy bike, and my parents would never know who I saw, what I did and where I was. Unless I wanted to tell them.
Freedom!
Bingo!
