I restarted the wi-fi while my nan was watching her show
Why would you do that when your nan was watching her show?
It was a show about a cancer surviving mother, cancer survivors don't deserve a happy ending
It's rude to ruin someone else's show while they're watching it. Your disagreements with the show don't matter.
I'm doing this for myself. I don't care about my nan.
You sound selfish. What if someone turned off your show or game while you were enjoying it? You wouldn't like it.
