OOooooh man. My family doesn't do that but I was trying to show my friend my favorite movie once and it just felt like half the time she wasn't watching and was on her phone but I didn't want to be rude and call her out on her behavior and just turned into a sad pile of sad because it was trying to show her a thing that I really loved and it was just super disrespectful.
You totally have the right to be angry
