I don't want to share my ps4 with my nephew
What is your reason for not wanting to share your ps4 with your nephew?
He's a spoiled child and uses my ps4 all the time. I can't enjoy playing with myself alone
While I understand that kids often like to play video games, I agree that their play time should also be limited. You should talk to your nephew about it and set times when he can and cannot use the game console. Otherwise he might grow up to be a brat with no respect.
I hate kids and he makes the game choices for me.
Well it is good to limit the time your nephew spends playing games. However, not letting your nephew play because you hate him is not a very good reason.
