Act 2,Scene 2. Q2:
At one point in the conversation Peter tells Anne that he has no friends and that he does not need friends. I do agree that you do not need friends to be happy. You do not need to have friends to be happy, all you need to be happy in life is family. In life you can be lonely and still be happy because you can make yourself happy by playing games that only requires one person.
If you don't have any friends you can still be happy by playing video games. This is how I agree with Peter, you do not need friends to be happy.
