To what extent do you manage children's lives?

On another thread, a jelly mentioned that s/he leaves most decisions up to their child, unless doing so may affect health/safety of said child. Paraphrasing, can’t remember the exact words.

To what extent is this true for you? Would you attempt to force a child to, for example…

* ... say ‘please’ and ‘thank you’
* ... loan a toy to someone else
* ... tidy her room
* ... fake gratitude when receiving a present
* ... address adults with their proper titles
* ... zip up his coat
* ... do homework
* ... clear her plate/eat greens
* ... go to bed at a set time
* ... wear a helmet when riding a bike
* ... hold your hand while near busy streets

For the purposes of this question, our imaginary child is about seven, but feel free to include any other points you deem relevant.
