As others have pointed out in Scotland you can get married at 16. I don't know if the law is the same in England but up here you can also prevent your parents knowing how you are doing at school and indeed knowing anything much about what is going on in your life. Although obviously in return they have no legal obligation to support you over 16 and provide a roof over your head. 16 year old voted in the referendum. And do some pretty mature things from 12. To suggest you can't go away to a B&B for two nights is ridiculous.
