Is AUTHOR wrong in the post ? POST : My 7 year old nephew came over this weekend with my SIL, and I happened to be playing Tetris99 on the TV. 

After watching me play a while, he asked if he could try. I lovingly but sternly told him that he could not. The game keeps track of my all of my stats, and I didn't want him ruining my win ratio. 

This is where my SIL stepped in, and asked if he could just try it out. I told her that if she wanted, she could pay for a Nintendo online account for him and I'd be glad to let him play on my switch. 

I also offered to let him play Zelda or Mario or Smash Brothers. Here's the kicker. I even offered to let him play Puyo Puyo Tetris, which is BASICALLY THE SAME GAME. 

This is when he started crying and throwing a fit. Seeing as my SIL clearly did not know how to parent, I simply undocked the switch and stepped away from all the drama. 

I later found out from my wife that the SIL was very upset and left soon after. 

Granted, the Nintendo Switch was a gift from them, but I don't think that gives their son to come over and act like he owns the place. I should also mention that I pay for the Nintendo Switch Online acccount.

She hasn't contacted me to apologize for her son's behavior, but I asked my wife to let her know that if she wants to venmo us the twenty dollars I'd be glad to set up his account for him. 

I get that kids sometimes throw tantrums, but I feel like giving in (like my SIL wanted me to) only reinforces that type of behavior. My wife thinks I should have let him try, but I don't even let her play on my account, so why would I make an exception for him? 

AITA for refusing to let my nephew play on my Tetris99 account?
