> You were a teenager once, I'm sure you can remember how little influence your parents actually had over how you actually spent your time.

There might be bias here if one remembers one's own teenage years, because I'm sure many teenagers _think_ their parents don't have influence over them. If you ask the parents though I'm sure many would agree aren't fully in control, but do notice they have a lot of influence still.

Personally, the older I grow, the more I realize how much influence in general my parents actually had over me.
