I'm looking forward to getting rid of my wife's 13-year-old nephew.
Is there something you dislike about your wife's nephew in particular?
I just feel like he is an extremely annoying little kid.
Sometimes hanging out with adolescents can be tiresome, but you should make an effort if they're family. When you married your wife, you accepted her family as your own. If you try to alienate her family, she's going to resent you.
I'm looking forward to kicking the kid back to his parents. They already hang out with his cousin Monkey. They can take care of him.
You should really watch the words you say when referring to your partner's family members. Wanting to get rid of your partner's family is not the right attitude when it comes to wanting to have a good relationship.
