I want to ask for/about his xbox
Why do you plan on asking about his xbox?
Because I want to play with him and he still doesn't let me play
It seems like it is fine for you to ask about the xbox. Maybe you can get a better understanding of his thought process.
Yea I want to figure out why he has a problem with it.
Yea there is no issue with wanting to play. It is great that you plan on asking him before using it.
