I want to tell a bunch of kids to stop wasting money on watching Endgame in the theater back to back to back
What issues do you have with people watching movies multiple times?
I think the people should stop wasting their money watching the same thing.
When we criticize others, we are not helping but embarrassing them. You should mind your own business in matters that don't concern you at all.
You're right. I should mind my own business.
When it comes to other people's enjoyment, you should. Fun is fun and lecturing people on how to have fun is rude.
