You realize clapping is mainly a social thing right?

I watched Star Wars ep 3 in theaters and the entire audience would erupt whenever Yoda did something badass.

It honestly made the whole experience that much more memorable because everyone around you is equally hyped up and enjoying the show.

How is it any different than laughing at a comedy show? Should everyone not laugh when something that’s meant to be laughed at happens? Should no one cry during emotional scenes?
