I'm going to pause my little brothers Wi-Fi to punish him.
Do you think pausing his Wi-Fi will get his attention?
Yes, because he's always online.
It can be annoying when siblings don't listen to you, but you shouldn't resort to punishing them. Petty punishments will only irritate them, instead you should try to have a thoughtful conversation with them. If your brother isn't doing a good job of listening to you, maybe ask him when a good time to talk would be.
Shut-Up! All I have to do is to pause the Wi-Fi and my little brother is already obeying.
That doesn't make it right. You should talk through your issues instead of trying to control him like that.
