ELI5: why is it that in all movies and TV shows, characters never end a conversation on the phone by saying "goodbye"? Instead they simply hangup, regardless of genre or tone.

I've observed this every time I've watched a movie or TV show.

Movies and TV shows are supposed to show only the bits that matter. Screen time is limited and you want to keep your viewers focused. You don't see characters having their breakfast, having a shower, shaving, taking a poop, etc because they are mundane and don't contribute to the plot.
