Parenting

Q:

My first question is: In Islam, when does a child have the right to go outside and maybe socialise or even go to the mosque and come back by themselves. Say a general ruling for maybe a boy who is 13-14 years old.

My second question is: Up to what extent is an older sibling allowed to punish a younger sibling i.e. corporal punishment or verbal? 

My third question is: If your parents say something like "I don't care about what sunnah or fatwah says, it's about what I say! It's about me!" how do you respond in a respectful way.

Parents are responsible for their children

Q: Nowadays kids dont tend to listen to parents. They always want it there way either by staying in their own bedroom or come down with the family or even they are meant to be studying but they dont want to and if they do they'll do it when they want even though advising them etc. So in this case what should one as parents do? Do they let them be how they want and just keep advising them. What should be done? Also what should be done if the parents and child argue because of that?
