I need some reasons why we should not use her phone in the movies I have it's distracting it's a waste of money and I need one more

Answer: The experience would be much better, you'd be isolated from the social media world for 1-3 hours, giving you time to just relax without worrying about any type of messages or emails or anything. It also would be a better way for you to not be making distractions to the others watching the movie.
